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

What should I do with it?
Homework Statement
Given potential r=2m on the surface of the sphere which meets the Laplasian equation (triangle)u=0 and is u(2,theta,psi)=5sin(theta)sin(0.25psi). I need to find the potential of sphere center. Can anyone help me?
