6 Preface has been used as a value for the last 000 years. This number actually represents polygon of Exhaustion Method of Archimedes (0 BC) of Syracuse, Greece. This is the only one geometrical method available even now. The concept of limitation principle is applied and thus this number is attributed to the circle. In other words, of polygon is a borrowed number and attributed/ thrust on circle as its value, as the other ways, to find the length of the circumference of circle, has become impossible with the known concepts, principles, statements, theorems, etc. From 1660 onwards, has been derived by infinite series also, starting with John Wallis of UK and James Gregory of Scotland. This number was obtained by Madavan of Kerala, India, adopting the same concept of infinite series even earlier i.e The World of Mathematics has recognized very recently, that Madavan is the first to invent infinite series for the derivation of John Wallis and James Gregory too invented the infinite series independently though later in period (George Gheverghese Joseph of Manchester University, UK). C.L.F. Lindemann (188), Von K. Weirstrass and David Hilbert have called as a transcendental number. The basis for their proof was Euler s formula e i (Leonhard Euler, Swiss Mathematician, ). With their proofs, squaring of circle has become, without any doubt, an unsolved geometrical problem. Thus, the present thinking on is the number. is, value which is an approximation and squaring of circle is impossible with the At this juncture, the true and an exact value equal to was discovered by the grace of God in March, 1998 after a struggle of 6 years (from 197) adopting Gayatri method. Hence, this value is called the Gayatri value as the Gayatri method has revealed the true value for the first time to the World. It was only a suspected value then, and however, it was i

7 not discarded, by this author. He continued and confirmed 1 as the real value with Siva method, Jesus method and later with many more methods only. A dilemma has thus crept into the minds of the people, which number or is the real value. One responsibility before this author was to clear this dilemma. And, therefore, a book was written collecting the work done in the past 1 years and titled Pi of the Circle in 010, and is available in the website The second responsibility before this author was also, to search for any flaw in the derivation of the present value of equal to As a result of continuous search for 16 years further deep, two errors have been identified. And one paper has been published. One is, that, belongs to the polygon and not to the circle. The second error is, to call of the circle as a transcendental number. They (Lindemann, Weirstrass and Hilbert) may be right in calling and not. Why? It has been shown in earlier paragraph that Euler s formula is the basis in calling as a transcendental number. In the formula e i + 1 0, refers to radians equal to and not constant 3.1. constant has no place for it in the above formula. When 3.1 is involved in the Euler s formula, the formula becomes wrong. Is it acceptable then to call constant as transcendental number even though this has no right of its participation in the above formula? However, it is acceptable still, if one agrees that radians constant 3.1 or radians is identical to constant 3.1 Mathematics may not accept this howler. Thus, on two counts i.e., is a polygon number and calling it as a transcendental number, based on radians The present work on unfortunately, is confusing. These are the two simple errors to be rectified immediately. Here, the NATURE has kindly entered and rectified the errors by revealing Gayatri is also done, by IT s grace. value. It is exact and is an algebraic number. Squaring of circle ii

10 How did this Zoology Lecturer get encircled himself in 197 in Mathematics? Some people are curious to know, how did this student of Zoology enter and entrench himself in this field of mathematics. Here is a brief narration: This author loves book reading very much. One day in 197, while reading an encyclopedia he saw square, triangle, trapezium and so on and found constant for circle alone in r and r and such constant was not there for other constructions. He questioned himself, Why. Why led to Why not without for circle too. He thought many days. One day he inscribed a circle in a square and found the diameter of the inscribed circle and the side of the superscribed square equal. He was surprised and felt happy that he got the clue to make real, the question Why not without. He thought and thought, did many things, searched, studied, enquired fellow mathematicians, did physical experiments, on-and-off, for next 6 years. Being a government college teacher, he was transferred in the mean time, from Piler ( ) to Kadapa, to Nagari, to Anantapur and finally to Chittoor (in December 1995). No answer to his question of 197. He was 6 when question came, waited another 6 years and lost self confidence. He was like a man swimming on the surface of the ocean looking down and striving hard to take hold of the wanted pin with its visible blurred image lying on the bottom of the ocean. Man looks up when he is helpless. This was what happened to him also. He went to the nearby temple of Mother Goddess Durga (at Chittoor) in 1998 and prayed to HER. He gave a word to the goddess. When he gets answer and succeed in finding formulas for the iv

11 area and circumference of circle without equal to /7, he will keep himself away from receiving awards, royalties, positions and avoid felicitation functions, meetings etc. on account of future discovery. Surprisingly, one Mr. Ramesh Prasad a physics teacher, next neighbor to this author when discussed with him this long pending problem after the promise to the Goddess before giving a clue he asked this author how did he had been doing. The answer to him was, as inscribed circle, it is smaller in size compared to the larger superscribed square the concept of difference had been a dominating point. With this answer, Mr. Prasad told this author to look at the problem, at the concept of ratio also and not only the factor of difference. This author received this idea of Mr. Prasad and that whole night worked on the problem and prepared an article and was sent to the Indian Institute of Technology, Kharghpur, Mathematics Department, next morning. The department was impressed with the paper and cautioned this author, was not /7 and it was in its reply with encouraging comments. There, the search did not stop. Second question came anew. The new question made this author why should there be /7, 3.116, By March, 1998, during the rejuvenated search Gayatri Method, Siva method came successively after many many many failures. Next 16 years, continuous search has been focused on confirming, the correctness of as value. This author thanks the reader for this attentive reading. v

I (Jul-Aug. 01), PP -8 Pi treatment for the constituent rectangles of the superscribed square in the study of exact area of the inscribed circle and its value of Pi (SV University Method * ) R.D. Sarva Jagannadha Reddy Abstract: Pi value equal to is derived from the Exhaustion method of Archimedes (0 BC) of Syracuse, Greece. It is the only one geometrical method available even now. The second method to compute is the infinite series. These are available in larger numbers. The infinite series which are of different nature are so complex, they can be understood and used to obtain trillion of decimals to with the use of super computers only. One unfortunate thing about this value is, it is still an approximate value. In the present study, the exact value is obtained. It is A different approach is followed here by the blessings of the God. The areas of constituent rectangles of the superscribed square, are estimated both arithmetically, and in terms of of the inscribed circle. And value thus derived from this study of correct relationship among superscribed square, inscribed circle and constituent rectangles of the square, is exact. Keywords: Circle, diagonal, diameter, area, radius, side, square I. Introduction Square is an algebraic geometrical entity. It has four sides and two diagonals which are straight lines. A circle can be inscribed in the square. The side of the square and the diameter of the inscribed circle are same. This similarity between diameter and side, has made possible to find out the exact length of the circumference and the exact extent of the area of the circle, when this interrelationship between circle and its superscribed square, are understood in their right perspective. The difficulty is, the inscribed circle is a curvature, though, its diameter/ radius is a straight line as in the case of side, diagonal of the square. When we say a different approach is adopted, it means, these are entirely new to the literature of mathematics. The universal acceptance to the new principles observed in the following method is a tough job and takes time. However, as the following reasoning ways are cent percent in accordance with the known principles, understanding of the idea is easy. To study the different dimensions, such as, circumference and area of circle, constant is inevitable. Similarly, to understand perimeter and area of the square, a and a are adopted and hence, no constant similar to circle is necessary in square. In the present study, the area of the square is divided into five rectangles. The areas of rectangles are calculated in two ways: they are: 1. Arithmetical way and. In terms of of the inscribed circle. Finally, the arithmetical values are equated to formulas having, and the value of is derived ultimately, which is exact. II.

The final result, 1 in this unification process, the real value is identified, and is, Key words: Arbelos, area, circle, diameter, diagonal, Golden Ratio, Perimeter, value, side, square I. Introduction The geometrical entitles and concepts such as circle, square, triangle, Golden Ratio have been studied extensively. The Golden Ratio is the ratio of two line segments a and b (when a < b) such that a b. b a b The ratio a , while the reciprocal b b 5 1 a Notice the relationship between the decimals. It suggests that 1 1. (A.S. Posamentier and I. Lehmann, 00, : A Biography of the World s Most Mysterious Number, Page 16). Archimedes (0 BC) of Syracuse, Greece, called the area arbelos that is inside the larger semi circle, but outside the two smaller semi circles of different diameters. By its shape it is also called as a shoemaker s knife. The Golden Ratio and the arbelos of Archimedes are different concepts. But in this paper by the grace of God, it has become possible to see that these two concepts too have an interesting and unexpected inter relationship between each other (one). Further, this relationship has an extended relationship also with the circle (two). It is a well known fact that there exists simple and understable relationship between circle and square (three). As circle, square are related, their combined interrelationship has been extended to value also (four). There is, thus, a divine chain of bond (of four interconnecting relations) exists, among square, circle, Golden Ratio, arbelos and value. (Here value means a true/ real/ exact/ line-segment based value. The stress here, on the adjectives to, has become necessary, because of Polygon is attributed or thrust on circle. In other words, this number to circle is a borrowed number from polygon and its 1 existence thus can not be seen in the radius of the circle, naturally. However, the new value (unlike with official value ) is inseparable with radius and is, here, humbly submitted to the World of Mathematics: Area of the circle 7r r r r r r Circumference of the circle 6r r 1 In support of the above formulae, this paper also chooses and confirms that the real value is Page 8

It has already been established that this area of the full circle is equal to the area of the shaded region called arbelos. 9. To calculate the area of the arbelos we have the following formulas. q d q h and where h perpendicular line KJ 5 diameter of the circle LKM h radius of LKM circle. 10.

(when a circle is inscribed in a square, or when a square is created from the four equidistant tangents on a circle, the length of the circumference of the inscribed circle can be demarcated in the perimeter of the superscribed square. It is called rectification of the circumference of the circle). Part III (Area of the arbelos) Let us calculate now the area of the arbelos with the known two values, official value and new one called Gayatri value. 15. With official value (S. No. 10) x x (S. No. 11) 16. With Gayatri value (S.No. 10) x (S.No. 11) 17. Finally, we obtain two different values representing same area of the arbelos of Archimedes. Official value gives: and Gayatri value gives: Which one is the actual value for the area of the arbelos? The answer can be found in Part IV. Part IV 18. In the Figure 1 we have Golden Ratio, HB equal to Let us divide area of the arbelos of S.No. 17 with the Cube of Golden Ratio and 16 multiply it with of the formula, derived in the S.No.1, which finally gives the area of the square 1 ABCD, equal to 1. The value that gives the exact area of the square equal to 1 is confirmed as the real value. Here, the Golden Ratio decides, the real value, by choosing the correct area of the arbelos of Archimedes of S.No Area of the arbelos obtained with official value (S.No. 17) Let us use simple calculator for the value of cube of Golden Ratio, which gives Area of the arbelos obtained with Gayatri value (S.No. 17). Let us repeat steps of S.No. 0 here: Page 11

25 A study that shows the existence of a simple relationship among square, circle, Golden Ratio.. As the exact area of the superscirbed square is obtained, it is clear, therefore, that, the real value is III. Conclusion It is well known that there exists a simple relationship between circle and square. In the present study, it is clear such simple relation also exists between Golden Ratio and arbelos of Archimedes.

Keywords: - Arbelos, area, circle, diameter, squaring, side I. INTRODUCTION Circle and square are two important geometrical entities. Square is straight lined entity, and circle is a curvature. Perimeter and area of a square can be calculated easily with a and a, where a is the side of the square. A circle can be inscribed in a square. The diameter d of the inscribed circle is equal to the side a of the superscribed square. To find out the area and circumference of the circle, there are two formulae r and r, where r is radius and is a constant. constant is defined as the ratio of circumference and diameter of its circle. So, to obtain the value for, one must necessarily know the exact length of the circumference of the circle. As the circumference of the circle is a curvature it has become a very tough job to know the exact value of circumference. Hence, a regular polygon is inscribed in a circle. The sides of the inscribed polygon doubled many times, until, the inscribed polygon reaches, such that, no gap can be seen between the perimeter of the polygon and the circumference of the circle. The value of polygon is taken as the value of circumference of the circle. This value is In March 1998, it was discovered the exact value from Gayatri method. This new value is In 188, C.L.F. Lindemann and subsequently, Vow. K. Weirstrass and David Hilbert (1893) said that was a transcendental number. A transcendental number cannot square a circle. What is squaring of a circle? One has to find a side of the square, geometrically, whose area is equal to the area of a circle. Even then, mathematicians have been trying, for many centuries, for the squaring of circle. No body could succeed except S. Ramanjan of India. He did it for some decimals of His diagram is shown below. Then the square on BX is very nearly equal to the area of the circle, the error being less than a tenth of an inch when the diameter is 0 miles long. S.

27 Squaring of circle and arbelos and the judgment of arbelos in choosing the real Pi value (Bhagavan With the discovery of squaring of circle has become very easy and is done here. Archiemedes (0 BC) of Syracuse, Greece, has given us a geometrical entity called arbelos. The shaded area is called arbelos. It is present inside a larger semicircle but outside the two smaller semicircles having two different diameters. In this paper squaring of circle and squaring of arbelos are done and are as follows. Squaring of inscribed circle QD is the required side of square Squaring of arbelos YB is the required side of square II. PROCEDURE 1. Draw a square and inscribe a circle.

For questions why, what and how of each step, the known mathematical principles are insufficient, unfortunately. So, as the exact area of ABCD square equal to 1 is obtained finally with new value. The new value equal to 1 is confirmed as the real value. This is the Final Judgment of arbelos of Archimedes. III. CONCLUSION This study, proves, that squaring of a circle is not impossible, and no more an unsolved geometrical problem. The belief in its (squaring of circle) impossibility is due to choosing the wrong number as value. The new value 1 has done it. The arbelos of Archimedes has also chosen the real value in association with the inscribed circle and the ABCD superscribed square. International organization of Scientific Research 69 P a g e 19

34 International Journal of Latest Trends in Engineering and Technology (IJLTET) Aberystwyth University Method for derivation of the exact π value R.D. Sarva Jagannadha Reddy Abstract - Polygon s value of Exhaustion method has been in vogue as π of the circle for the last 000 years. An attempt is made in this paper to replace polygon s approximate value with the exact π value of circle with the help of Prof. C.R. Fletcher s geometrical construction. Keywords: Circle, diagonal, diameter, Fletcher, π, polygon, radius, side, square I. INTRODUCTION The official π value is It is considered as approximate value at its last decimal place, always. It implies that there is an exact value to be found in its place. a, a, ½ab etc are the formulas of square and triangle which are derived based on their respective line-segments. Similarly, radius is a line-segment and a need is there to have a formula with radius alone and without π. The following formulas are discovered (March, 1998) from Gayatri method and Siva method. 7r r 1. Area of Circle r πr r r. Circumference of Circle 6r + π r ; where r radius and d 1 1 πd d d d where d diameter side of the superscribed square In the Fletcher s geometrical construction there are two line-segments. They are radius and corner 1 length. To find out the area of the shaded region in which corner length is present Professor has given 1 π. Fig-1: Professor s Diagram (by courtesy) II.

Inscribe a circle with centre O and radius ½. Side of the square is 1. E, F, G and H are the midpoints of four sides. Join EG, FH, EF, FG, GH and HE. Draw four arcs with centers A, B, C and D and with radius ½. Now the circle-square composite system is divided into 3 segments of two different dimensions, called S 1 segments and S segments. Number them from 1 to 3. There are 16 S 1 and 16 S segments in the square and 16S 1 and 8S segments in the circle. Square: ABCD, AB Side 1, AC Diagonal ; Circle : EFGH, Diagonal diameter AC JK 1 JK Diameter 1 Side; Corner length ; OL OK radius 1 1 ; LK OK OL From the diagram of Fletcher the area of the shaded segment cannot be calculated arithmetically. The diagram of the Siva method helps in calculating the area of the shaded segment. How? Shaded area of Fletcher is equal to two S segments 19 and 0 of Siva method. This author, in his present study, has utilized radius/ diameter as usual, and a corner length, in addition, of the construction to find out the arithmetical value to the shaded area. A different approach is adopted here. What is that? As a first step the shaded area is calculated using four factors. They are of Fig-. AC and BD, diagonals ( ) ; Vol. Issue July ISSN: 78-61X

With this, the above formula becomes π 1 1 π The accepted value for π is With this π, the area of shaded region is equal to And, with the new π value derived above, the area of the shaded region is equal to So, this method creates a dispute now ? Which π value is right i.e. is or The study of this method is extended further to decide which π value is the real π value? To decide which π is real, a simple verification test is followed here. What is that? We have a line segment LK LK is part of the diagonal along with the corner length KC. So, in the Second step, an attempt is made to obtain the LK length, from the area of the shaded region. How? Let us take the reciprocal of the area of the shaded region; 1 1 Area of theshaded region of official π and with new π Vol. Issue July ISSN: 78-61X 3

It may be questioned why one should divided that value. The answer is not simple. Certain aspects have to be believed, without raising questions like what, why and how at times. Official π New π of new π value is in total agreement with LK of Fig.. i.e and differs however with of official π from 3 rd decimal onwards. If this argument is accepted, the present π value is not approximate value from its last decimal place, but it is an approximate value from the 3 rd decimal. IV. CONCLUSION From the beginning to the end of this method, various line-segments are involved. Professor Fletcher s construction is analyzed arithmetically with the line-segments of the Siva method. This arithmetical interpretation has resulted in the derivation of a new π value, equal to 1. The new value is exact, algebraic number. REFERENCES [1] C.R.

Introduction The Holy Bible has said value is equal to 3. Mathematicians were not satisfied with the value. They thought over. Pythagorean theorem came in the mean time. A regular polygon with known perimeter was inscribed in a circle and the sides doubled successively until the inscribed polygon touches the circumference, leaving no gap between them. Hence this method is called Exhaustion method. The value of the perimeter of the inscribed polygon is calculated applying Pythagorean theorem and is attributed to the circumference of the circle. This method was interpreted, first time, on scientific lines by Archimedes of Syracuse, Greece. He has said value is less than 3 1/7. Later mathematicians have refined the Exhaustion method and found many decimals. The value is and this value has been made official. From 15 th century (Madhava (150) of South India) onwards infinite series has been used for more decimals to compute of geometrical method. Notable people are Francois Viete (1579), Van Ceulen (1596), John Wallis (1655), William Brouncker (1658) James Gregory (1660), G.W. Leibnitz (1658), Isaac Newton (1666), Machin (1776), Euler (178), S. Ramanujan (191), Chudnovsky brothers (1989). The latest infinite series for the computation of value is that of David Bailey, Peter Borwein and Simon Plouffe (1996) and is as follows: i i0 16 8i 1 8i 8i 5 8i 6 Using above formula Yasumasa Kanada of Tokyo University, Japan, calculated trillions of decimals to with the help of super computer. Mathematics is an exact science. We have compromised with an approximate value. Hence, many have tried to find exact value. This author is one among the millions. What is? It is the ratio of circumference of a circle to its diameter. However, in Exhaustion method, perimeter of the inscribed polygon is divided by the diameter of the outside circle. Thus violates the definition of. This is about the value of. Next, about the nature of. C.L.F. Lindemann (188) has said is a transcendental number based i on Euler s formula e 1 0. In Mathematical Cranks, Underwood Dudley has said s only position in mathematics is its relation to infinite services (and) that has no relation to the circle. Lindemann proclaimed the squaring of the circle impossible, but Lindemann s proof is misleading for he uses numbers (which are approximate in themselves) in his proof. Hence, pre-infinite series days of geometrical method is approached again to find out exact value and squaring of circle. This author has struggled for 6 years (197 to 1998) and calculated the exact value of in March, The following method calculates the total length of circumference and thus the exact value has been derived from it. Procedure: Draw a square. Draw two diagonals. Inscribe a circle. Side a, Diagonal a, Diameter is also a d. 1) Straighten the square.

Let us say circumference x. Circumference 3 diameters x 3a esc esc end segment of the circumference of the circle. 3) When the side of the square is equal to a, the radius of the inscribed circle is equal to a/. So, the radius is 1/8 th of the perimeter of the square. ) The above relation also exists between the end segment of the circumference of the circle and the end segment of the perimeter of the square. a Thus as radius of the inscribed circle is to the perimeter of the square (a), i.e., 1/8th of it, so also, is the end segment of the circumference of the circle, to the end segment of the perimeter of the square.

Nagar, Tirupati , A.P., India Abstract: Till very recently we believed was the final value of.and no body thought exact value would be seen in future. One drawback with is, that it is not derived from any line-segment of the circle. In fact, is derived from the line-segment of the inscribed/ circumscribed polygon in and about circle, respectively. Surprisingly, when any line-segment of the circle is involved two things happened: they are 1. Exact value is derived and that exact value differs from from its 3 rd decimal onwards, being Two geometrical constructions of Hippocrates of Chios, Greece (50 B.C.) and Prof. Alfred S. Posamentier of New York, USA, and Prof. Ingmar Lehmann of Berlin, Germany, are the supporting evidences of the new value. They are detailed below. Keywords: value, lune, triangle, area of curved regions I. Introduction In the days of Hippocrates, value 3 of the Holy Bible was followed in mathematical calculations. He did not evince interest in knowing the correct value of. He wrote a book on Geometry. This was the first book on Geometry. This book became later, a guiding subject for Euclid s Elements. He is very famous for his squaring of lunes. Prof. Alfred S. Posamentier and Prof. Ingmar Lehmann wrote a very fine collaborative book on. They have chosen two regions and have proved both the regions, though appear very different in their shapes, still both of them are same in their areas. These areas are represented by a formula r 1. The symbol r is radius., here must be, the universally accepted Every subject in Science is based on one important point. It would be its soul. In Geometry, the soul is a line-segment. The study of right relationship between two or more line-segments help us to find out areas, circumference of a circle, perimeters of a triangle, polygon etc. For example, we have side in the square, base, altitudein the triangle. The same concept is extended here, to show its inevitable importance in the study of two regions of Professors of USA and Germany. The lengths of the concerned line-segments have been arrived at and associated with r does not agree with the value of line-segments of two regions. However, the new value has agreed in to-to with the line-segments of the two regions of the Professors. This author does believe this argument involving interpretation of r 1 with the linesegments, is acceptable to these great professors and the mathematics community. It is only a humble submission to the World of Mathematics. Judgment is yours. If this argument in associating line-segment with the formula looks specious or superficial, this author may beexcused. II. Procedure The two methods are as follows: 1. Hippocrates' Method of Squaring Lunes And Computation of The Exact Value Archimedes's procedure for finding approximate numerical values of (without, of course, referring to as a number), by establishing narrower and narrower limits between which the value must lie, turned out to be the only practicable way of squaring the circle. But the Greeks also tried to square the circle exactly, that is they tried to find a method, employing only straight edge and compasses, by which one might construct a square equivalent to the given circle. All such attempts failed, though Hippocrates of Chios did succeed in squaring lunes. Hippocrates begins by noting that the areas of similar segments of circles are proportional to the squares of the chords which subtend them 9 Page 9

43 Supporting Evidences To The Exact Value From The Works Of Hippocrates Of Chios, Alfred S. Consider a semi-circle ACB with diameter AB. Let us inscribe in this semi-circle an isosceles triangle ACB, and then draw the circular arc AMB which touches the lines CA and CB at A and B respectively. The segments ANC, CPB and AMB are similar. Their areas are therefore proportional to the squares of AC, CB and AB respectively, and from Pythagoras's theorem the greater segment is equivalent to the sum of the other two. Therefore the lune ACBMA is equivalent to the triangle ACB. It can therefore be squared.

Sarva Jagannadha Reddy ABSTRACT: value is it is an approximation, and it implies the exact value is yet to be found. Here is a new method to find the most sought after exact value is actually is the value of inscribed polygon in a circle. It is a transcendental number. When line-segments of circle are involved in the derivation process then only the exact value can be found thus obtained is an algebraic number and hence squaring of circle is also done in the second part (method-3) of this paper. KEYWORDS: Circle, Diagonal, Diameter, value, Radius, Square, Squaring of circle I. INTRODUCTION METHOD-1: Computation of tail-end of the length of the circumference over and above three diameters of the Circle The Holy Bible has said value is 3. Archimedes (0 BC) of Syracuse, Greece has said value is less than 3 1/7. He has given us the upper limit of value. In 3 1/7, 3 represents three diameters and 1/7 represents the tail-end of the circumference of the circle (d circumference) In March, 1998, Gayatri method said the value as 1 length of the circumference of a circle over and above its 3 diameters as equal to equal to 1. 1/7 of Archimedes of Gayatri method and its tail-end of the 1 when the diameter is In the days of Archimedes there was no decimal system, because there was no zero. Archimedes is correct in saying the tail-end length of the circumference is less than 1/7. How? Gayatri method supports 1 Archimedes concept of less than 1/7 by giving. The denominator part of the fraction, is actually, less than 7 of 1/7. He is a great mathematician. This fraction has become possible because of the introduction of zero in the numbers 1 to 9 and further consequential result of decimal system of his later period. If he comes back alive, with his past memory remain intact, Archimedes would say, what he had visualized in 0 BC has become real. II. PROCEDURE Let us see how this tail-end value of circumference is obtained: Draw a circle with Centre O and radius a/. Draw four equidistant tangents on the circumference. They intersect at four prints called A, B, C 33 P a g e 33

47 New Value: Its Derivation and Demarcation of and D, creating a square ABCD. The diameter of the circle EF is also equal to the AB side of the square. Draw two diagonals AC and BD. Their values are a. Perimeter of the square is equal to a. In this circle-square composite system there are now 3 types of straight lines and one circumference which is a curvature. The straight lines are 1. Perimeter of the square,. Two diagonals and 3. Diameter of the circle. The values of these straight lines are known and exact. The length of the circumference is unknown and hence this method is to find out its exact length with the help of known lengths of three types of straight lines. Let us repeat here again the perimeter (a) of the square and the sum of the lengths of two diagonals a are the outcome of the tangents on the circumference. It is clear therefore that the curved circumference reflects its true length in all the straight lines of square and circle. We know very well that there are three diameters and some length called tail-end in the circumference. Circumference 3 diameters + tail end length Tail-end length is unknown and hence it is called x. 3d + x circumference Diameter is equal to side of the square i.e. d a Let us rewrite 3d + x as 3a + x To find out the length of the x We take the help of all the straight lines. The reciprocal of the two diagonals plus the perimeter of the square and when this product is multiplied by the square of the diameter ( side), will give x value. 1 1 a a x a a 1 1 Circumference 3 diameters (3a) + tail-end length (x) 3a a a Circumference of the circle d a So, 1 a a P a g e 3

48 New Value: Its Derivation and Demarcation of The length of the circumference is obtained by superscribing a square. The correct understanding of the relationship among perimeter, diagonals of the square and the diameter of the circle ( side of the square) results in knowing the exact length of the tail-end of the circumference (x), what the great mathematician 1 1 Archimedes has said is less than 1/7 is proved now to be The denominator of Gayatri method is less than 7 of 1/7 of 3 1/7 of Archimedes.

The demarcated length of the 1 circumference of the circle is BA + AD + DC + CH a + a + a + a a The area of the circle is now bounded by a curvature called the circumference. In this method this area can have a straight-lined boundary. In this process the value of plays important role. The official value is With this value let us locate the area: 1. Square ABCD, Side AB a; AC BD diagonals a ; O Centre. Inscribed a circle with centre O and radius a ; side diameter a 3. OF OG Radius; FOG triangle; OF a ; FG hypotenuse a ;.

It has become impossible. 11. As an alternate, let us try to locate, the area with the guidance of the Circumference of the Gayatri 1 method i.e. a, and with this, the Gayatri value is P a g e 36

CONCLUSION New value is exact and it is an algebraic number and squaring of circle has be done by demarcating, the area of a circle in a square. REFERENCES [1].

Nagar, Tirupati , A.P., India Abstract: It is universally accepted that as the value of. It is thought an approximation, at its last decimal place. It is a transcendental number and squaring a circle is an unsolved problem with this number. A new, exact, algebraic number is derived and verified with a proof that is followed for Pythagorean theorem. It is proved here squaring of circle and rectification of circumference of a circle are possible too. Keywords: Pythagorean thorem, circle, square,. I. Introduction Official value is It is obtained from the Exhaustion method, which is a geometrical method. This method involves the inscription of a polygon in a circle and increased the sides of the polygon, until the inscribed polygon touches the circle, leaving no gap between them. The value is actually the length of the perimeter of the inscribed polygon. And it is not the value of circle. There was no method till yesterday to measure the circumference of a circle, directly or indirectly has four characteristics: 1) It represents polygon, ) It is an approximation, 3) It is a transcendental number and ) It says squaring a circle is impossible. And such a number is attributed and followed as of the circle based on limitation principle, because of the impossibility of calculating, the length of the circumference of circle and in such a situation this field of mathematics has been thriving for the last 000 years. From 150 Madhavan of South India and a galaxy of later generations of mathematicians have discarded geometrical construction and have introduced newly, the concept of infinite series. In this paper geometrical constructions are approached again, for the derivation of value. New value has been derived. It is It is an exact value, an algebraic number and makes squaring of circle possible and done too. II. Procedure Siva method for the area of the circle of 1 st square ABCD Construction procedure Draw a square ABCD. Draw two diagonals. O is the centre. Inscribe a circle with centre O and radius ½. E, F, H and J are the mid points of four sides. Join EH, FJ, FH, HJ, JE and EF. Draw four arcs taking A, B, C and D as centres and radius ½. Now the circle square nexus is divided into 3 segments. Number them 1 to 3. 1 to 16 segments are called S 1 segments. 17 to 3 segments are called S segments. 17 to, S segments are outside the circle. 5 to 3, S segments are inside the circle.

First square has an inscribed circle divided into 3 segments of two dimensions called S 1 and S segments, each category of 16 in number. And areas of these segments are calculated using the following two formulas a a S S 1 and 3 3 which are obtained by solving two equations (in Square 1) 16 S S a Area of the square (Eq.1) 16 S S a / Area of the inscribed circle (Eq.) This method is called as Siva method. In the present method: Siva Kesava method, second square is joined to the 1 st square. One side CB is common to both the squares. The second square is similarly divided, as in the case of 1 st square, into 3 rectangles. Rectangles are also of two dimensions each category of 16 numbers. The areas of each type of rectangle is equal to S 1 and S segments of the 1 st square. These rectangles are formed, based on the division of common side of the both the squares. The areas of rectangles agree cent percent with the above two formulas of Siva method, where value is 1. Thus, the division of 1 st square is exactly duplicated in the second square, except for the difference, in the 1 st square, 3 segments are curvy linear, and in the nd square, 3 segments are rectangles, naturally, of straight lines. Now let us see how the common side CB is divided. 1. Squares 1 ABCD, BZTC. Side diameter of the inscribed circle 1 3. KP Parallel side to the side DC. OM ON radius ½ 5.

So, each length is 1/ Finally, the nd square is divided into 16 rectangles of one dimension equal in area to S 1 segments of 1 st square and 16 rectangles of nd dimension, equal in area to S segments of 1 st square. 16.

QX 1 TC; XW WT CS SQ QX + XW + WT + TC + CS + SQ In the first square we have seen that the length of the circumference of the inscribed circle is the outer edge of the 16 S 1 segments. In the nd square also the outer edges of the 1 st and nd rows of 16 rectangles are equal to Thus, Siva Kesava Method supports the value 1 obtained by earlier Gayatri, Siva, Jesus methods. 7. And also, the curvy linear 16S 1 and 16S segments of 1 st square are all squared in the nd square. III. Conclusion Two squares of same sides are drawn with one common side. Circle is inscribed in one square. Areas of square and its inscribed circle are calculated from their constituent curvy linear segments. The correctness of areas of constituent segments are verified with that of the areas of rectangles of the adjoining square. All the values thus are proved correct. 0 Page

Sarva Jaganndha Reddy ABSTRACT : Circle and square are soul and body of the subject of Geometry. All celestial bodies in the Cosmos are spherical in shape. Four equidistant tangents on a circle will give rise to a square. A circle can be inscribed in a square too. Thus, circle and square are two inseperable geometrical entities. is a fundamental mathematical constant. The world believes as value for the last 000 years. Yet it is an approximate value. Continuous search for its exact value is going on, even now. God has been kind. The exact 1 value is not a myth. It has become real with the discovery of. It is a very tough job to convince the world that the new finding is the real value. In this paper, the exact length of the diagonal of the inscribed square form the length of an arc of the superscribed circle is obtained as a proof. KEYWORDS: Circle, circumference, diameter, diagonal, perimeter, square I. INTRODUCTION The geometrical constant, called, is as old as human civilization. In the ancient days, contributions on was very admirable from the Eastern parts of the World. The Founding Father of Mathematics: Hippocrates of Chios (50 BC) has not touched the value of. But his work on the nature of circular entities such as squaring of lunes, semicircle and full circle is unparalled in the History of Mathematics.The present value, could not understood Hippocrates work and its greatness. What is the reason? This number is not the of the circle. It is the value of the polygon. It was derived using Pythagorean theorem. Pythagorean theorem gives exact length to a hypotenuse which is a straight line. Circumference of a circle is not a straight line. It is a curvature. Hence, of polygon has failed to understand the greatness of Hippocrates. In other words, is not a number at all. After a long waiting of 000 years by trillions of scholars NATURE has revealed its true length of a 1 circumference of circle and its value. The value is derived from Gayatri method. It was discovered in March This worker is the first and fortunate humble man to see this fundamental truth, and at the same time, made this author responsible to reveal to the whole world, its total personality. He was cautioned by the Nature, through Inner Voice, further, not to shirk his responsibility till the end, till the world welcomes it, and continue to search speck by speck naturally, respecting the Cosmic mind of the Nature, with indomitable determination, and fight single handedly against the conservative attitude and die like a warrior defeated, if situation of reluctance to acceptance still persistsfrom the remote past to the present, the period of study of is divided into two periods: the period of geometrical dependence in the derivation of value and the nd period from 1660 AD onwards till today, the period of dependence on infinite series, dissociating totally geometrical analysis in the derivation of value. In the present and second period, the number is considered as a number only and nothing to do with the definition of the ratio of circumference and diameter of a circle. The paradox is, geometry is forgotten in the derivation of value but searched for the same, in squaring of a circle. Finally, this number has gained four characteristics: 1. Though it is a polygon number, established itself as a number of circle.. Though an approximate number it ruled the world for many centuries as a final value. 3. Though it doesn t belong to a circle has commented squaring of circle as an unsolved geometrical problem.. Though it has gained a status of transcendental number with the definition of the fact that cannot be calculated by a combination of the operations of addition, subtraction, multiplication, division, and square root extraction (Ref.1) is derived actually in Exhaustion method, applying the Pythagorean theorem, and invariably with the involvement of 3. Further, the moment this number discared the association of Geometry, it has started a new relationship in 1 P a g e 3

57 To Judge The Correct-Ness Of The New Pi Value Euler s formula e i +1 0 with unrelated numbers which are themselves approximate numbers. C.L.F. Lindeman (188) has called number as a transcendental number based on Euler s formula. Here again, there is a discrepancy in choosing, in the Euler s formula. In the formula, means radians and not, constant 3.1 Are they both, radians and constant are identical? constant is divine, whereas radians equal to is, human creation and convenience. In the Euler s formula radians is involved and the resultant status of transcendence has been applied to constant. Let us rewright e i as e 1 0. Is it right and acceptable?it may not be wrong in calling that is a transcendental number but it is definitely wrong when number is called a transcendental number and with a consequential immediate statement squaring of a circle is impossible. The major objection is, the very definition of is the ratio of circumference and diameter of a circle. So, this discrepancy led to the conclusion that is not, infact, a number.in its support, we have the work of Hipporcrates. Hippocrates had squared a circle even before any text book on Mathematics was born; His text book is the basis of Euclid s Elements too. As Hippocrates did square the circle it implied an algebraic number. Further, Lindemann is also right in calling as transcendental number and not right, if he calls number as transcendental. Here, there is a clarity of opinion thus is a polygon number (and attributed to circle). In this paper the diagonal length is obtained from the actual length of the circumference of the circle. II.

CONCLUSION In circle, there are circumference, radius and diameter. In square, there are perimeter, diagonal and side. When a circle is superscribed with the square, circumference, side, diagonal and perimeter of square coexist in an interesting relationship. In this paper, this relationship is studied and the diagonal length is obtained from the arc of the circumference. This is possible only when the exact length of the circumference is known. A wrong length of circumference obtained using a wrong value gives only wrong length of diagonal.

D. Sarva Jagannadha Reddy This author though a non-medical graduate (Zoology) was offered a Medical post, Tutor in Physiology in St. John s Medical College, Bangalore, India Abstract:, 3.1, 3.116, are being used as values at school level calculations and at 7 the research-level calculations. Many more numbers are found in the literature for. A method, therefore, is necessary to decide which number is, the real value. The following method chooses as the real value. Keywords: Circle, corner area, diameter, side, square. I. Introduction Circle and square are basic geometrical constructions. To find out perimeter and area of a square there are present two formulae a and a, where a is the side of the square. Similarly, to calculate the circumference and the area of a circle, there are two formulae, r and r, where r is the radius and is a constant. The concept represents, the ratio of the circumference and the diameter of its circle. Thus, the constant is a natural and divine concept. We have radians equal to 180 0, which is a human creation and convenience. For the last 000 years, has been ruling the mathematical world as the value. In March 1998, a new value was discovered by Gayatri method and supported by more than one hundred different geometrical proofs in the last 16 years. The time now has come to decide, which value, is present value or is new value, real? Here is a simple procedure. The nature has created a square and a circle. All the celestial bodies in the Cosmos are spherical in shape. It shows the basic architectural design of the physical world from the Cosmic mind. We see on paper that it has not only created an exact relationship between the circumference and the diameter of a circle and also, the Nature has established an interesting relationship between square and its inscribed circle too. This relationship is taken as the guiding principle to decide the real value from many numbers. Hence, this method is called the Natural Selection. Page 3 7

61 The Natural Selection Mode To Choose The Real Pi Value Based On The II. Procedure Draw a square. Inscribe a circle. Square ABCD, Side AB a, AC BD diagonal, O centre. EF diameter d a Area of the square a Area of the circle d a where a d Square area Circle area Corner area Square area Corner area a x a a a a Divide x by 3. In Siva method, it is found that when the circle square composite geometrical construction is divided symmetrically, the number of segments are x Thus, we obtain finally, the formula which is equal to the value over and above 3. As 3 8 of the diagonal of a square, so also is for the circumference of the inscribed circle, and it is an established fact by this work. And further, the number 3 represents a common associating factor of the inscribed circle and the square. The procedure followed here is in steps. Step 1, Calculates the areas of square and circle Step, Obtains corner area by deducting circle area from the square area Step 3, Squarearea Corner area and Square area 1 Step, Corner area 3 At the 1 st step while calculating the area of the circle, known value is used. In this paper two values are chosen: the official value and the new value 1 Any value enters at the 1 st step, and it s decimal part reappears at the th step. Thus, the resurrection of the decimal part of value is observed at the th step. And this happens only when the real value is taken in the 1 st step. Any other number, if used, does not reappear fully, at the th step. Side diameter a 1 Area of the square : a 1 x 1 1 I.

62 The Natural Selection Mode To Choose The Real Pi Value Based On The The decimal part of the official value is Only first two decimals 0.1 reappeared in the th step, instead of all the decimals. II. Let us repeat the above process with the new value d Area of the circle x 1 x 1 x Square area Circle area Corner area Square area Corner area Square area Corner area 3 3 The decimal part of the new value is All the decimals have now reappeared in the th step. There are some more numbers if one looks at the Internet. Prominent numbers that are attributed to, besides of Archimedes, are (Laxman S. Gogawale), 3.15 (Mohammadreza Mehdinia), (from PHI) etc. All these values too have failed when processed in the above steps, to resurrect at the th step. S. No. Proposed/accepted numbers to Resurrected decimal part over and above 3 of value (Official value) Archimedes is much nearer to the real value than though it has been 7 considered as final value to is farthest low value to. number of Golden Ratio is the next closest to the real value attributed to. Out of all the numbers attributed to value detailed in the above Table, only one number of 1 has resurrected itself at the end, with its all the decimals, over and above 3. Hence 1 is the true value. Other numbers have succeeded in coming back with one or two first decimals only beyond 3. Hence, these numbers have, failed in the race to qualify themselves, in the selection, by the natural geometrical construction as a true value. III. Conclusion There are many values in the literature. Two values and are very popular. 7 Third value equal to is added now to the existing values saying that the new Page 36 9

63 The Natural Selection Mode To Choose The Real Pi Value Based On The value is the only true value. In this paper a simple method is found, to choose, the real value. This method chooses 1 as the real value, which is the exact and an algebraic number. REFERENCES [1].

Sarva Jagannadha Reddy Abstract: Circle, square and triangle are basic geometrical constructions. constant is associated with the circle. In this paper, circle-triangle interlationship chooses the real value of and calculating the area of the triangle involving of the inscribed circle. The alternate formula to find the area of the triangle is 3 3 d. This formula has a geometrical backing. 1 Keywords: Altitude, base, circle, diameter, perimeter, triangle I. Introduction The official value is It is an approximation, inspite of having trillions of its decimals. A new value to was discovered in March The value is Both the values have their own supporting arguments. Triangle is another geometrical entity. Its area is calculated using the formula ½ ab, where a altitude and b base. In this paper, a different formula has been derived to find out the area of the equilateral triangle based on the of its inscribed circle. The formula ½ ab gives the area of the triangle. No other formula is necessary for the area of triangle. The main purpose of derivation of new area formula of triangle is, to test the correctness of value involved in the new formula. One advantage in using the new formula for area of the triangle is, the resulting value tally s exactly with the value of ½ ab only, when the chosen value is correct one. If the wrong/ approximate value is involved in the new formula, it does not give exact value of the triangle. In other words, out of the two numbers and only one number, gives the exact area of the triangle. The number which fails in giving exact value to the area of the triangle is decided as the wrong value. Procedure Draw a circle with centre O and radius d. Draw three equidistant tangents on the circle. The tangents intersect at A, B and C, creating an equilateral triangle ABC. DE is the hypotenuse of DOE triangle or the chord of the circle.

In this paper, a new formula d is 1 derived. This formula by giving the exact area of ABC triangle shows, that circle and the equilateral triangle are clearly interrelated and are not very different as we have been believing. The benefit we derive by using this formula is, this formula chooses the real value, discarding other approximate values attributed to. This method alone, for the first time in the history of mathematics, acts as a testing method of and boldly says 1 Archiemedes upper limit of 3 or is a lower value compared to the real number. 7 7 Post script As it is proved in this paper that the real value is 1 based on the area of the triangle ABC, it has made possible to demarcate the length of the circumference of the inscribed circle in the straight-lined perimeter of the ABC triangle.

Sarva Jagannadha Reddy /D3, Sri Jayalakshmi Colony, S.T.V. Nagar, Tirupati , A.P., India Abstract: Hippocrates has squared lunes, circle and a semicircle. He is the first man and a last man. S. Ramanujan is the second mathematician who has squared a circle upto a few decimals of equal to The squaring of curvature entities implies that lune, circle are finite entities having a finite magnitude to be represented by a finite number. Keywords: Squaring, lune, circle, Hippocrates, S. Ramanujan,, algebraic number. I. Introduction Hippocrates of Chios was a Greek mathematician, geometer and astronomer, who lived from 70 until 10 BC. He wrote a systematically organized geometry text book Stoicheia Elements. It is the first book. And hence he is called the Founding Father of Mathematics. This book was the basis for Euclid s Elements. In his days the value was 3 of the Holy Bible. He is famous for squaring of lunes. The lunes are called Hippocratic lunes, or the lune of Hippocrates, which was part of a research project on the calculation of the area of a circle, referred to as the quadrature of the circle. What is a lune? It is the area present between two intersecting circles. It is based on the theorem that the areas of two circles have the same ratio as the squares of their radii. His work is written by Eudemus of Rhodes (335 BC) with elaborate proofs and has been preserved by Simplicius. Some believe he has not squared a circle. This view has become very strong with the number a polygon s value attributed to circle, arrived at, from the Exhaustion method (EM) prevailing before Archimedes (0 BC) of Syracuse, Greece, and refined it by him, hence the EM is also known as Archimedean method. This number has become much stronger as value, and has been dissociated from circle-polygon composite construction, with the introduction of infinite series of Madhavan (150) of South India, and independently by later mathematicians John Wallis (1660) of England, James Gregory (1660) of Scotland. With the progressive gaining of the importance of as value from infinite series, the work of squaring of circle of Hippocrates has gone into oblivion. When the prevailing situation is so, in the mean time, a great mathematician Leonhard Euler ( ) of Switzerland has come. His record-setting output is about 530 books and articles during his lifetime, and many more manuscripts are left to posterity. He had created an interesting formula e i +1 0 and based on his formula, Carl Louis Ferdinand Lindemann ( ) of Germany proved in 188 that was a type of nonrational number called a transcendental number. (It means, it is one that is not the root of a polynomial equation with rational coefficients. Another way of saying this is that it is a number that cannot be expressed as a combination of the four basic arithmetic operations and root extraction. In other words, it is a number that cannot be expressed algebraically). Interestingly, the term transcendental number is introduced by Euler. When all these happened, naturally, the work on the Squaring of circle by Hippocrates was almost buried permanently. This author with his discovery in March 1998 of a number from Gayatri method, and its confirmation as value, from Siva method, Jesus proof etc. later, has made the revival of the work of Hippocrates. Hence, this submission of this paper and restoring the golden throne of greatness to Hippocrates has become all the more a bounden duty of this author and the mathematics community. II. Procedure I. Squaring of Lunes-(1) Hippocrates has squared many types of lunes. In this paper four types of lunes are studied. Consider a semi-circle ACB with diameter AB. Let us inscribe in this semi-circle an isosceles triangle ACB, and then draw the circular are AMB which touches the lines CA and CB at A and B respectively. The segments ANC, CPB and AMB are similar. Their areas are therefore proportional to the squares of AC, CB and 39 Page 56

70 Hippocratean Squaring Of Lunes, Semicircle and Circle AB respectively, and from Pythagora s theorem the greater segment is equivalent to the sum of the other two. Therefore the lune ACBMA is equivalent to the triangle ACB. It can therefore be squared. The circular arc AMB which touches the lines CA and CB at A and B respectively can be drawn by taking E as the centre and radius equal to EA or EB. 1. AB diameter d. DE DC radius d/ 3.

Let ABC be an isosceles right angled triangle inscribed in the semicircle ABOC, whose centre is O. AB and AC as diameters described semicircles as in figure. Then, since by Ecu.

The best known of these are the crescents (or lunulae) of Hippocrates. By the theorem of Thales the triangle ABC in the first figure is right angled: Thus p m + n. The semicircle on AB p has the area A AB p /8; the sum of the areas of the semicircles on AC and BC is A AC +A BC (n + m )/8 and is thus equal to A AB. From this it follows that: The sum of the areas of the two crescents is the area of the triangle. 3. AB diameter d. BC radius d/ 3d 5. AC 6. DF d/ 7. DE d 3d 3d d 8. EF 9. GH d/ 30.

Squaring of circle Consider two concentric circles with common centre O and radii such that the square of the radius of the larger circle is six times the square of the radius of the smaller one. Let us inscribe in the smaller circle the regular hexagon ABCDEF. Let OA cut the larger circle in G, the line OB in H and the line OC in I. On the line GI we construct a circular segment GNI similar to the segment GH. Hippocrates shows that the lune GHIN plus the smaller circle is equivalent to the triangle GHI plus t he hexagon. 63.

V. Post Script The following are the points on which some thinking is necessary: is accepted as value is a transcendental number. 3. As this polygon s value is accepted as of the circle, circle and its value have become transcendental entities.. The concept of transcendental number vehemently opposes squaring of circle. Latest developments is the new value is the exact value. 7. This number is an algebraic number, being the root of x 56x Squaring of circle is done with this number. Conclusion 9. Hippocrates did square the circle is a transcendental number it is correct can not square a circle, - is also correct. Final verdict 1. As Hippocrates did the squaring a circle, it amounts to confirming that circle and its value are algebraic entities. It implies that as is a borrowed number from polygon and attributed to circle, called a transcendental number, said squaring a circle an unsolved geometrical problem, the final verdict is, all are correct, except one, i.e. attributing of polygon to circle. Hence is not a value at all. References [1]. T. Dantzig (1955), The Bequest of the Greeks, George Allen & Unwin Ltd., London. []. P. Dedron and J.

Keywords: Exact Pi value 1/ (1- ), Squaring of circle, Hippocrates squaring of lunes. I. Introduction Squaring a circle is defined as constructing a square having an area equal to that of a given circle. It is also called as quadrature of the circle. This concept has been there from the days of Rhind Papyrus (1800 B.C) written by a scribe named Ahmes. Hippocrates of Chios (50 B.C) has squared lunes, full circle and semicircle along with lunes. He fore saw the algebraic nature of the value. value has failed to find a place for it in the squaring of lunes. Though the World of Mathematics has accepted his squaring of lunes, they became silent for why is a misfit in his constructions. Further, there is a false opinion that Hippocrates could not square a circle. However, Hippocrates did square a full circle and a semicircle along with a lune. In both the cases squaring a lune, squaring a circle along with a lune the new value, 1 has explained perfectly well the constructions of Hippocrates. Thus the propositions of Hippocrates which remained theoretical all these 00 years, have become practical constructions with the discovery of 1. It is clear therefore, we have misunderstood Hippocrates because, we believed as the value of. I therefore apologize to Hippocrates on behalf of mathematics community for the past mistake done by us. And to atone the academic sin committed by us, I bow my head and dedicate the explained parts (for details: Pi of the Circle, last chapter: Latest work, Pages from 73 to 81) to Hippocrates, in James Gregory (1660) has said squaring of circle is impossible. His view has been confirmed by C.L.F. Lindemann (188) based on Euler s formula e i Von K. Weiertrass ( ) and David Hilbert (1893) have supported the proof of Lindemann by their proofs. S. Ramanujan (1913) has squared a circle upto some decimals of Prof. Underwood Dudley doesn t accept Lindemann s proof because this is based on numbers which are approximate in themselves. Now, the exact value is discovered. It is 1 1. It is an algebraic number. The following is the procedure how to square a circle. whose value is II.

D. Sarva Jagannadha Reddy Abstract: There is only one geometrical method called Exhaustion Method to find out the length of the circumference of a circle. In this method, a regular polygon of known number and value of sides is inscribed, doubled many times until the inscribed polygon exhausts the space between the polygon and circle as limit. In the present paper, it is made clear, that the value for circumference, i.e of polygon, attributing to circle is a lower value than the real value, and the real value is adopting error-free method. Key words: Circle, corner length, diameter, diagonal, polygon, side, square. I. Introduction The Holy Bible has said value is 3. The formula for circumference of a circle is d, where is a constant and d is the diameter. When the diameter is 1 the circumference is equal to value. When, a hexagon is inscribed in a circle of ½ as its radius, the perimeter of hexagon is equal to 3. It means, the circumference is greater than 3, because hexagon is an inscribed entity in the circle. With the unit diameter of circle, circumference and/or value is exchangeable, because, both are represented by a single number. There were many values for (Chung Hing, 50 AD), (Wang Fau, 50 AD), (Liu Hui, 63 AD), (Aryabhata, 99 AD). From Francois Viete (1579) onwards the value has become an accepted value. It is a well established fact that the value is However, two things which are associated with this number have not satisfied some scholars of mathematics. They are is a borrowed number of polygon, attributed to circle, believing in the logic of limitation principle and being an approximate number, made super computers too have failed to find the exact value and. Assertively, this number has said, squaring a circle impossible, being it is a transcendental umber. High school students, now and then ask, when mathematics is an exact science, how is it possible we have many values are being used, for example, 3.1, 3.116, Nature has been kind. Exact value has been found at last. A few papers in support of the exact value have been published (in Reference). Surprisingly the new value is struggling very hard still for its approval. All the time, the work done on has been cited, saying, the past generation or the present workers could not be wrong. Thus, the new value (through was discovered 16 years ago, in March 1998 is yet to be accepted. From March 1998, with the discovery of , this worker has been struggling to find evidences in support of new value, and also struggling much more in search of an error in the derivation of There are some similarities and some differences between present and new values. The similarity is, in Exhaustion method a polygon is inscribed in a circle and in the new method a circle is inscribed in a square. The differences are many: 1. Present value represents the perimeter/ area of the polygon and attributed to circle; the new value represents the area of the inscribed circle only in a square (called Siva method in Reference). Here, square helps but does not lend its value to circle.. Present value is derived applying Pythagorean theorem meant for straight lines. New value is derived adopting entirely a new approach for which no previous proofs/ statements are available. 3. Present value is a transcendental number and new value is an algebraic number.. Present value says squaring of a circle is an impossible idea and Page

80 The unsuitability of the application of Pythagorean Theorem of Exhaustion Method, in finding the whereas the new value squared a circle. It also, circled a square (i.e., constructing a circle whose circumference and/or area equal to the perimeter and/ or area of a square respectively. For example, if the side of a square is 1, the perimeter would be and its area would be 1. Circling a square means we have to find out a radius geometrically of circle whose length of the circumference is and/ or area of the circle is 1. In this paper, present value-to some decimal places is obtained using the new value 1, showing, circle, polygon and square are not different geometrical entities and their interrelationship, if understood correctly, may help in the derivation of present value from the new value also. If this idea is accepted, an algebraic number like 1 is also, capable of giving rise to, a transcendental number like It leads to the creation of a new doubt, is is really a transcendental number? There are 3 examples cited below, linking present and new values and To drive to the point an elaborate explanation is chosen and here and there repetitions too appear. II. PROCEDURE Example-1 The following formula gives the present value upto 5 decimal places. When my work on deriving the new value of equal to was submitted, I was advised by many to think how to derive the present value cautioning me as the new one was wrong. In obedience, I hereby submitted the following formula giving the number exact upto five decimal places where 00 To get the same value ( ) from the Classical method of Archimedes, we have to travel a long way using the following general formula to calculate the length of the perimeter of the inscribed polygon of 1536 sides starting from 6 sides, in a circle Side sn r r r sn A geometrical line segment for Let us draw a circle with diameter 9 and radius 9/. Cut the circumference at one point and straighten it and further divide it into 00 equal segments. Similarly, divided the diameter into 3 equal segments. 1/3 rd diameter + one segment length of circumference Page 30 67

81 The unsuitability of the application of Pythagorean Theorem of Exhaustion Method, in finding the Example- Archimedes inscribed a polygon of 96 sides with the circle and gave perimeter of the polygon as equal to 3 10/ When the diameter of the superscribed circle is 1 unit, the perimeter value. Prof. Constantine Karapappopulos of University of Patra, Patra, Greece has suggested a formula for the 1 3 Archimedian minimum as equal to 3 1 in the range of The proposed formula for x to gives the circumference of the circle as equal to Perimeter of Polygon x Circle connecting link Circumference of Circle is obtained by the calculation method. One need not set aside it on the reason that the above factor is based on the calculation method. This factor or circle connecting link can be viewed as a clue or guiding factor for further analysis. On close observation one finds the denominator and the numerator of the link are symmetrical and give us a right relationship between the inscribed polygon and the superscribed circle. Example-3 Classical method involves the inscription of polygon in the circle. Starting with the known perimeter of a regular polygon (here we start with a regular hexagon) of n sides inscribed in a circle, the perimeter of the inscribed regular polygon of n sides can be calculated by the application of Pythagorean theorem. Let C be a circle with centre O and radius r, and let PQ s be a side of a regular inscribed polygon of n sides having a known perimeter. Then the apothem, OM u is given by r s side RQ w of he inscribed polygon of n sides is found from polygon is known. hence the sagetta, MR v r u is known. Then the w v s Page 31 hence the perimeter of this 68

No. n First Side PQ s ns Perimeter Circumferen ce s/ t Apothem r t u Sagetta r u v Succeeding side v t w Let us analyse the above Table. The calculation is started with a regular polygon of 6 sides having the perimeter equal to 3. The sides of polygon are doubled for 9 times and now the inscribed polygon has 307 sides and its perimeter circumference of circle value is equal to Thus, the number of sides are increased 51 times finally The length of the perimeter has increased from to The correct value is From the above Table, it is possible to find the exact length only upto i.e. 6 decimal places only with 307 sides of the polygon. ABCD Square; EFGR Circle; AB Side NQ diameter 1; AC Diagonal ; AN QC Corner length; Diagonal diameter AC NQ 1; Hexagon STGUVE In the Classical method of calculating perimeter/ circumference/ in the above table, number of sides of the inscribed polygon plays an important role. The derivation is started with 6 sides and ended with 307 sides. The perimeter of the hexagon is 3 and the perimeter of the polygon of 307 sides has increased to Page 3 69

83 The unsuitability of the application of Pythagorean Theorem of Exhaustion Method, in finding the Starting no. of sides of the polygon 6 Ending no. of sides of the polygon 307 Starting perimeter 3 Ending perimeter Present value New value In the following formula a relation is shown between two values: present value and new value as in the above two examples. Squareof thestarting no.of sides Ending no.of sides Present value (correct upto 6 decimals) New value Diagonal diameter The lengthy process involved in the above Exhaustion method is represented in a single formula In the Exhaustion method Pythagorean theorem is applied invariably appears in every aspect of calculation. The result obtained from the above formula using is much more accurate at 7 th decimal place than what it is ( ) obtained in the Exhaustion method in the table. In the Exhaustion method RQ is the hypotenuse and is the side of the inscribed polygon. And in the above formula diagonal diameter corner lengths on either side of the diameter also play an important role. Hence, it has become possible that the new value has given the present value (to some decimals). Let us understand, in much more clear terms, the above formula. There are four factors in the Exhaustion method. They are No. of sides of the hexagon 6 Perimeter of the hexagon ½ x 6 3 No. of sides of the final polygon 307 Perimeter of the final polygon Let us divide final sides by the sides of the beginning polygon i.e. hexagon Let us divide corner length AN + QC into 51 parts. AB Side NQ Diameter 1 AC diagonal Corner length AC NQ diagonal diameter 1 Let us divide above length into 51 parts Multiply the above value with the no. of sides of the beginning polygon (hexagon) Deduct the above value from the new value value (to some decimals) So, the corner length 1 is divided into 51 parts which gives the present Page

84 The unsuitability of the application of Pythagorean Theorem of Exhaustion Method, in finding the 6. In this process corner length 1 is taken for consideration. 7. In the Exhaustion method the hypotenuse RQ in Fig. is taken for consideration and proceeded successively for many times. 8. AC is the hypotenuse of the triangle DAC of Fig. and RQ is the hypotenuse of the triangle RMQ. 9. How does the length over and above 3 diameters of the circumference of the circle is arrived in deriving the new value? The answer is very simple. Let us divide the corner length QC only of Fig- by Side AB diameter NQ 1 Corner length QC Diagonal diameter AC NQ 1 QC Divide QC by Now, the length of circumference 3diameters and add to the 3 diameters. 10. When we compare two ways of arriving the exact length of circumference of a circle, it is clear in Exhaustion method the perimeter of the inscribed polygon is increased slowly by doubling the number of sides of the previous polygon. Thus, the number of sides have been increased from 6 to 307, it means it has been increased 51 times. In other words, we have divided corner length into 51 parts. In the second approach in the arrival of length of the circumference, the corner length is Corner length QC divided at one stroke with So, 3 sides + QC Thus there are two values for the length of the circumference of the circle of Exhaustion method and of Gayatri method 1. We can thus visualize a diagram of, containing a hexagon whose perimeter STGUVE is 3, next to hexagon, of inscribed polygon of 307 sides and further next and the circle EFGR, whose circumference is equal to with radius ½. III. Conclusion 1 There are now two values and In the Exhaustion method, perimeter of the polygon is attributed to the circumference of the circle. As the inscribed polygon is smaller one, the value must be lesser than the exact length of the circumference of circle. This paper clearly shows the calculation error involved in the arrival of the actual length of the circumference ( ) of the circle. Hence, Exhaustion method is not suitable in arriving the of the circle. However, this study shows that both the values have a common-ness in their nature. In Exhaustion method while doing calculations involving squaring, square root etc. and only a few decimals have been taken. All the numbers are infinite numbers. So, the prolongation of round-off-error is universal throughout the calculations. And this has resulted in a lower value instead of the actual value. However, the new work has tried to overcome the error supposed to be in the Exhaustion method by adopting Gayatri method, Siva method, Jesus Page 3 71
