Dear Aditya

Your score in Exam 2 is 84 out of 100

Everything was right except

#2: the intergal of sin(x) is -cos(x) NOT sin(x), careless error leading to the wrong ans. :-3 points
(I was lenient, usually getting the wrong ans. can get you at most 5 points)

#7(d): -4 points. (PLEASE REVIEW THIS SUBTLE AND IMPORTANT TOPIC)

#9: PARTIALLY RIGHT WAY, WRONG ANSWER. The projection on
the xy-plane IS not the square {0<x,y<3} BUT THE DISC {x^2+y^2<=9}: -5 points
(The limit of integration are 0 to 3 AND 0 to sqrt(9-x^2)

#10: Right answer to the wrong question. I asked for the POINT not the value: -4 points
(I even put point in bold-face) READ THE QUESTION

Best wishes
