ok i that with the limits -2<Z<2 0<\theta<\pi 0<r<4 now do i need to change 4(x^2)y to 4(r^2)(cos^2\theta)sin\theta? when i integrate that get 0? I am not sure if that's correct.

[b]1.The problem asks " use the divergence theorem to evaluate the surface integral \int\int F.ds for F(x,y,z) = <x3y,x2y2,−x2yz> where S is the solid bounded by the hyperboloid x^2 + y^2 - z^2 =1 and the planes z = -2 and z=2. i know that the \int\int F.ds = \int\int\int divFdv...
