Homework Help: Reynolds Transport derivation?(or 1-form Stokes)

  1. Apr 29, 2010 #1
    1. The problem statement, all variables and given/known data
    The latex document for these equations wasnt updating correctly, so Ive included them as an attachment whereever there is a ... in the text

    Ok, Im trying to understand the Reynolds transport theorem, but i dont understand part of it.

    2. Relevant equations
    This is the actual equation Im specifically interested in:
    ...
    3. The attempt at a solution
    Now I know one term would be just the chain rule for f(phi)

    ...

    , but Im not sure how the derivative works for the other term to lower the order to a surface derivative.
    From texts I found, I guess the answer should be something like,

    ...

    but I dont really understand how to explicity take the derivative of the integral to lower the order.
