1. The problem statement, all variables and given/known data 2. Relevant equations I know that flux is ∫∫F[r(t,s)]dotted[∂r/∂s x ∂r/∂t]dtds 3. The attempt at a solution So I parameterized the equation y=x^2+z^2 as: x = s y = s^2 + t^2 z = t r(t,s) = [s, s^2+t^2, t] I take the partial derivative of r with respect to s and t and then take the cross product. I then that F[r(s,t)] and dot that with the cross product above. I then need the boundaries which I find to be 1/sqrt(2) ≤ s ≤ 1/sqrt(8) and 1/sqrt(2) ≤ s ≤ 1/sqrt(8) After integrating I get the answer 35/384 which says it's incorrect. I did the problem all over again and got the same exact answer. Any help?
