1. The problem statement, all variables and given/known data V.Field F(x,y,z)=<x^2 z, xy^2, z^2> where S is part of the plane x+y+z=1 inside cylinder x2 + y2 =9 2. Relevant equations Line integrals, Stokes Theorem, Parametrizing intersections... 3. The attempt at a solution I found the answer to be 81pi/2 using stoke's theorem and the double integral, but now I have to verify it using a line integral and I'm stuck. I think r(t) is supposed to = <3cos(t), 3sin(t), 1-3cos(t)-3sin(t)> but it just turns out so nasty I'm wondering if there are pieces I'm missing. Any help is appreciated.
