Helmholtz' Theorem Proof

  1. Jan 23, 2008 #1
    Hi everyone, new to this site and was wondering if anyone could help me out...

    I am trying to prove the following equation to be true but don't really know where to start. Supposedly, I should be finding the Laplacian first using spherical coordinates.

    ∇^2(1/|R|) = -4*pi*δ(R)

    where |R|= |r-r'| and R = r-r'

    and δ(R) = δ(r-r') = δ(x-x')δ(y-y')δ(z-z')

    I realize this is a mess with how it looks, but wasn't sure how to convert mathematica text into the thread window.

    Thanks for any help!

    Try using the divergence theorem. Can you show what you got so far?
