1. The problem statement, all variables and given/known data Evaluate the surface integral F * dr, where F=<0, y, -z> and the S is y=x^2+y^2 where y is between 0 and 1. 2. Relevant equations Divergence theorem 3. The attempt at a solution I just got out of my calculus final, and that was a problem on it. I used the divergence theorem and got div F = 0 + 1 - 1 =0 Therefore the triple integral and therefore the surface integral will return 0. Is this true? I thought it was too easy, I can't see why it wouldn't be true. Is there a limitation I glossed over?
