Homework Help: How do you find the normal component of a function F (Stoke's theorem question)

  1. Aug 13, 2009 #1
    1. The problem statement, all variables and given/known data
    This isn't really regarding any specific question, I am just wondering how do I find the normal component of a vector valued function along a surface S?

    Stoke's theorem says the integral over a curve of F (dot) dx is equal to the integral of curlF (dot) n dA over the surface bound by the curve. If I have a function F (you can make one up if it helps explain) to integrate over a surface , how do I find the normal component "n" that I need to use?
    2. Relevant equations

    3. The attempt at a solution

    Hi theneedtoknow! :smile:

    n isn't the normal component, it's the unit vector normal to the surface. :wink:

    For most surfaces, that should be fairly easy to find. :smile:
