    Potential of Sphere Center: Solve Laplacian Equation

    Thanks for Your help very much. This thing is a bit difficult for me, so I will ask a bit more. So the Laplasian operator in spherical coordinates is http://upload.wikimedia.org/math/8/2/7/8275dcad2a7a2f9587c996beb5cc8c37.png What should I do with it?
