Homework Help: EM- Flux through a cylindrical syrfacehelp asap, pls

  1. Nov 9, 2008 #1
    1. The problem statement, all variables and given/known data
    1. The expression F = [x,y,z] defines a vector field. Given the parametric representation of a surface S:[u cos v, u sin v, u^2] = r (u,v), where the parameters cover the ranges 0 ≤ u ≤ 2 and 0 ≤ v ≤ 2π, calculate the flux F through the surface S.

    2. Relevant equations
    How do i start this problem?

    3. The attempt at a solution
    I know the transformation equations for the cylindrical coordinates, and:
    flux=Int(E dot dA=Int(divergence of E d tao
    Im not sure if i should find the jackobian, but if so how do i work with the parametric representation vector r??

    P.S. sry about spelling
