(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Finding the potential.

2. Relevant equations

general solution of potential is in terms of spherical harmonics Y_l,m.

3. The attempt at a solution

My question is how do we know which l to choose given a boundry condition. for example if the potenial on the surface of a sphere of radius "a" = const*sin (theta) cos(theta). How do we know which l that corresonds to? or do we try all the l's and see which one works out?

Thanks
