GRADING: The final grade is a weighted average f: Hmewrk, Quizzes 10% Cmputer Prject 25% Exam #1 30% Final Exam 35% Grading Scale: A ; A ; B ; B 76-80; B ; C ; C 56-65; D 41-55; F

4 FALL 2017 Other Infrmatin: There will be weekly hmewrk assignments and tw quizzes. The hmewrk assignments, quizzes and exams are nt multiple-chice and are graded by hand. Integral part f this curse is the cmputer lab. We will meet in the Physics Department Cmputer Lab in SI-117A n: W September 6, W September 20, W Octber 4, W Octber 18, W Nvember 1, W Nvember 8 and M Nvember 20. We will wrk prblems in electricity and magnetism by using the sftware MathCad. Yu shuld save yur wrk n the CD/memry stick. On W December 6 each student will give me the CD/memry stick with all the prgrams and a printut f the results. Attendance f all lab sessins is bligatry and is included in the grading f the prject. All exams must be taken. Otherwise the final grade will be F regardless f the numerical grades. Attending the lectures is essential fr the prper understanding f the material. The students are respnsible fr all the material discussed in class. Attendance requirements are stated in the CSU Undergraduate Bulletin. Educatinal access is the prvisin f classrm accmmdatins, auxiliary aids and services t ensure equal educatinal pprtunities fr all students regardless f their disability. Any student wh feels he r she may need an accmmdatin based n the impact f a disability shuld cntact the Office f Disability Services at (216) The Office is lcated in MC 147. Accmmdatins need t be requested in advance and will nt be granted retractively. 4

6 FALL 2017 HOMEWORK #1 Griffiths Ch.1, Prblems: 3, 7, 11, 13, 15, 18; Examples: 9, 10, 11 Using the Cartesian unit vectrs x, y, z, write the vectr V pinting frm (2, -4, 1) t (0, -2, 0). Find its magnitude V and the angle it makes with the z axis. Given V1 = 3x +5y z; V2 =-2x +y 3z; V3 = 6x +5y -3z, cmpute: V1*V2; V1xV3; V1*(V2xV3); (V1xV2)xV3. Check that (V1xV2)xV3 = -V1(V2*V3) + V2(V1*V3). Cnsider a cube. Calculate the angle between the cube s diagnal and the face diagnal adjacent. Given V = y 2 zx + z 2 xy + x 2 yz, verify: *( xv) = 0; x ( xv) = ( *V) - 2 V WEDNESDAY, SEPTEMBER 6, 2017 Griffiths Ch.1, Prblems: 44, 45, 49. Griffiths Ch.2, Prblems: 2.
