Dear Daniel

Your score in Exam 2 is 90 out of 100

Everything was right except in 

#1 you did
the long way (not the clever way). That is OK,
but you did not explain how you got the right answer
from the monster integral in t that you had.
Did you use Maple?, if you did you had to state
the Maple line that did it. It looks like it came
out of nowhere: -5 points


#9: YOU DID NOT multiply by -1 (DOWNWARD NORMAL):
-5 points

Best wishes,
