Phsics Disquisition THE INVERSE DERIVATIVE The new algorithm of the derivative GuagSan Yu ( Harbin Macro Dnamics Institute. 1566, P. R. China ) E-mail:1951669731@qq.com ( 15.1.1 16.1.6 ) Abstract: The Newton's second law third law has proven to be wrong, his mistake is the derivative operation the limitation resulting. Therefore new derivative the computation method desiderate the creation, this is the Inverse Derivative algorithm. The Inverse Derivative is a kind of extension of the derivative computation, it is based on the derivative calculated generated, using most of the derivative formulas to converted adjusted. In the field of phsics mechanical engineering, Inverse Derivative ma be a large number of emploed, to replace original derivative computation method. Will produce the enormous profound influence. Ke Words: Inverse Derivative; Contrar Derivative; Inverse Differential; Contrar Differential; Inverse Integral PACS:.1.à v.1.de.7. c.1.ud 3.65.Fd Introduction This paper is in a basis of the derivative, bring forward a new calculation method Inverse Derivative. 1 The Inverse Derivative Principle For functions: f ( x ) In this case the derivative is: f' x d ( + ) f x x f x ' lim lim dx x x x x (1..1) (1..) It shows that when the increment Δx approaches zero, the limit of Δ /Δx namel the respect to x the derivatives. Here make incremental Δx approaches zero, which is ver important. It shows the derivative f ' ( x ) is a unit of differential dx to calculated. For example, when the derivative is represented with speed, it is in units of time, That is in time of unit, b changing the distance traveled, to represent the rate of change of speed. About Inverse Derivative, it is different from the derivative of it? First, look at the inverse function: Or: x g 1 x f (1..3) (1..4) 1

Phsics Disquisition Well, that is the Inverse Derivative: q f ( ) ' x ' lim lim qx x f f 1 + + 1 1 + (1..5) So the Inverse Derivative is recorded as [f 1 ( )]` +, x ` +, q /qx. Corresponds with the differential of derivative q qx also called Inverse Differential. Clearl, in the Inverse Derivative operations, is when incrementalδ approaches zero, forδ /Δx seek limit. Therefore, the Inverse Derivative [f 1 ( )]` + to indicate is with Inverse Differential q for the units to calculated. Here it with the derivative calculate, been have essentiall different. For example, when b the Inverse Derivative represented speed, it is with move distance for unit. That is within the distance of units, through experienced time its different, represent the speeds is different. This is with the derivative to record or described speed, is had significantl different. And it versus the thing the rule of phsics, even there will be different interpretations. So this is ver important. In the course of phsics, man calculations should be use the Inverse Derivative to calculate, it will be correct. For example, concerning force the calculate, decided size of the force, moving objects the speed or acceleration, is b the object the displacement, to direct reflection the energ of the movement of objects. In this time denote the object move the velocit acceleration, its at move the unit space b experienced the time, reflect then is the object locomotion energ to relativel to the densit of the time. So the force to calculate, regardless is a velocit or acceleration, all should regard that object move space to be unit, been proceed the computation. Adopt the Inverse Derivative algorithm namel. According to this principle, we discovered the Newton second law of the adoption derivative computation is wrong. And put forward to regard Inverse Derivative computation as fundamental, new that second laws of motion new the third laws of motion. Obviousl, the principle of the Inverse Derivative be near to derivative ver, been a derivative principle to exp. The Inverse Derivative quote the inverse function of the derivative, so it as if the reciprocal of the derivative operation. But increment Δ increment Δx that the position, does not change however in Inverse Derivative. This is for the sake of the habit of the traditional phsics in care concept, therefore just was changed b denominator the unit of the computation to numerator at this time, but denominator numerator of however the character did not change. For example while computing velocit or accelerations, is still the divide of distance of the move with undergo that the time. So the analtic formula of the Inverse Derivative is equals to will the analtic formula inside of the derivative, after exchange of the x of the variable will the numerator denominator exchange. And will function smbol changes to inverse function smbol. The Conversion of The Inverse Derivative Formula Because the principle of the Inverse Derivative is that principle to base on the derivative, so usuall be applicable to the derivative the circumstance, also will be applicable to the Inverse Derivative equall. For example concerning whether function can seek the derivative,the Inverse Derivative is opposite with derivative. When the image of function its shows whether can seek the derivative,well then at this image of function revolving 9, its whether can seek the Inverse Derivative to is same with it. It is obvious, the Inverse Derivative analtic formula just will the derivative analtic formula, the numerator denominator makes exchange. Therefore, from the analtic formula of the derivative, can will derivative differential the formula, conversion through simple adjustment to Inverse Derivative

Phsics Disquisition Inverse Differential the formula. For example the function that the sum difference that the derivative formula: d du dv ( u ± v ) ± dx dx dx u ± v ' u' ± v ' (..1) (..) Can to convert the sum difference that the Inverse Derivative formula: q q q u ± v qu ± qv [ u v ] + ± ' lim ( u + u ) ( u) ± ( v + v ) ( v ) q lim u ± v qu ± qv (..3) (..4) And the product the derivative formula: d dv du uv u + v dx dx dx uv ' uv' + vu ' (..5) (..6) Also can convert to the Inverse Derivative formula of the product: q q q uv uqv + vqu + u v [ uv ] + ' lim lim u + u v + v u v + v u + u v + q [ u v + v u + u v ]' uqv + vqu + qu qv (..7) (..8) And the derivative formula of the quotient: d u v du dx u dv dx dx v v (..9) u vu' uv ' ' v v (..1) 3

Phsics Disquisition Conversion to the Inverse Derivative formula is then: q v v + v q q v v + qv lim lim u x v u u v qx v qu u qv q v lim ( v + v ) v lim lim ( u + u ) u ( ) ( ) ( v + v ) v ( v + v ) v ( u + u ) u v u ( v + v ) v u + v ' u + u v u v + v + ' ( ) u ( qv ) u v u v q v v + qv ( v + v v ) v qu (..11) (..1) The derivative formula of the composite function: d d du dx du dx (..13) d d du ( f g ( x) ) f ( u) g ( x ) ' ' ' dx du dx (..14) Can convert directl to the formula of the Inverse Derivative: u q q qu lim lim lim x u x qx qu qx (..15) + + ( f g )' f ' g ' ( u ) q q qu + qx qu qx 1 1 (..16) The formula of the derivative of higher order(second order): d d d " ( ') dx dx dx (..17) Conversion the higher order(second order) Inverse Derivative formula is then: 1 q q f ( ) + x " " + 1 qx qx q x (..18) Above is that some in common use derivative formula, conversion to Inverse Derivative formula the 4

Phsics Disquisition method. In need can will more derivative principle, be to conversion quote for that the Inverse Derivative. 3 The Inverse Derivative Partial Derivative The Conversion The Inverse Derivative expressive, in realit can with the partial derivative to achieve. Therefore, the Inverse Derivative can convert to the partial derivative. Whereas, the partial derivative can also convert to the Inverse Derivative. For example the function of second variables: z f ( x, ) To the partial derivative is: (, + ) (, ) z f x f x z lim f '( x, ) z ' Be to partial differential at this time: z d z d f ' x f x + f x (, ) lim (, ) (, ) x x (3..1) (3..) (3..3) Then the Inverse Derivative is: q x ' lim lim qx x f f + 1 1 + Can treat Inverse Derivative as a function of second variables its obviousl: q (, ) z f x qx Usher in to be partial differential will this function of second variables: d z lim f x, + f x, lim f x, lim f x, x x (3..4) (3..5) (3..6) q d z lim f ( x, ) lim x qx (3..7) Then the Inverse Derivative be for a function of second variables, been it an partial differential. Therefore it can convert to partial differential of a partial derivative, some similar condition that the partial differential of partial derivative, also can convert to the Inverse Derivative. 4 The applied of the Inverse Derivative new second motion laws third motion laws The tpical applied of the Inverse Derivative, it is in new second motion laws third motion laws. New the second laws of motion: 5

Phsics Disquisition l ql F lim m m ma l t q t + (4..1) It too with mass the product representation force of the acceleration, but its acceleration is second order Inverse Derivative, record for a + to express it is different with that the derivative. Because at this time second order the Inverse Differential q t, just is among them the variable b the Inverse Derivative. So when the force changes, among them mass m with force is relation to geometric proportion, but its acceleration a + then is relation to an inverse proportion square with force. This will be caused a series of singular result, express for the same force, when the mass of the object is different, the mass of the force is with the value of the product of the acceleration is different, it will is. Theor deduce with experiment all denote, this is exactness is it. But Newton the second laws of motion the third laws of motion, because is an adoption derivative operation, therefore in realit is wrong. New the Inverse Derivative formula of the third laws of motion: ql 1 F m ql m q t q t F 1 ( ql ) m β β m β β ql β q t β q t (4..) (4..3) It is explained two objects interactional, the small object in mass suffers the larger dnamic acting force to action. Then when two mass is different the object interactional, two objects produces the different momentum, therefore its momentum is not conservation. New the third laws of motion expresses, the momentum is not conservation, for this reason classical mechanics inside, the momentum conservation law also is wrong. The above circumstance indicate, Inverse Derivative is in the phsics the mechanics to used, produce the strange result. There is evidence showing, Inverse Derivative is in electrodnamics or electromagnetics realms, also ma have the ver big use. 5 Inverse Integral The integral of the Inverse Derivative computes, being called the Inverse Integral. It computes with common integral, should has no too big differentiate. It is will the common integral the compute that the differential smbol, changing the smbol of the inverse differential is then. The principle method of its computation is similar is it. But although the superficial computing method is same, because of the character of the Inverse Derivative, the result that computation come out will still have ver big different. For example compute the force to does work is it: ql 1 1 W F qx m qx mu mu q t 1 1 m ql m 1 1 W F1qx qx β u u β q ( t β )( t β ) β (5..1) (5..) Express the same force action to the different object of two masses, the force to two the object those make the work is different. The object of small β times of the mass, b the force that big β times of make 6

Phsics Disquisition the work. This a kind circumstance gained the proof in of experiment of elasticit release of spring. This point also is ver important. So operation in above integral the experiment of the spring all expresses, the spring elasticit releases, to masses different the object, engender the different work. This a circumstance is shows, when the spring confront the different object in masses does the work, the energ is not conservation. For this reason Inverse Derivative the adduction of the Inverse Integral computation, cause some important phsics law been b shaken. Among them of the meaning is enormous. 6 Summing up Therefore b complement exp of the Inverse Derivative for derivative operation, is extremel important. In actualit adopt similar Inverse Derivative such method, to the thing come proceed measure or formulations, is also do not lack its example in fact. For example, the running that athletics compete the inside, is all in measure rule the distance, that consume the time. And is not in restrict time, run how much distances. For example in phsics, usuall the problem that discuss is, certain energ the action in stated the time. For example the force, electromagnetism force, electric quantit so forth. This paper inside mentions, is the classical mechanics the second third laws of motion, new the second third laws of motion that the force. Because of the adoption of the Inverse Derivative, the law of the some phsics was wrong b the proof. That ver much is ma that the similar circumstance, will exp to include the other one phsics course of electromagnetics so on. And creation important influence. Thereb discover put forward this kind of new computing method of the Inverse Derivative, the meaning is extremel important. To the development progress of human science, inevitable creation profound extensive influence. Acknowledgments The authors to thank the Editorial Office. The authors to thank references author.
