Dear Joe, Your score in Exam 2 is Y out of 100 Everything was right except #1: right (but way too complicated!) way, a better way (how it is meant to be done) is using the Fundamental Theorem of Line Integrals: -5 points #5: You integraded over all the WHOLE SPHERE, I asked for the section where x,y,z are all positive: -4 points #7(d): right answer, partially right way (the point is (1,1) so (0,y)->(1,1) is nonsense): -2 points #9: No answer, you started the right (but way too complicated way): -6 points Best wishes, Dr. Z.
