I'm having a lot of difficulty calculating the monopole and dipole moments for a dielectric sphere with surface charge of the form,(adsbygoogle = window.adsbygoogle || []).push({});

sigma(theta)=sigma(0)cos(theta)

If surface charge wasn't present and it was just a point charge I would be OK but I need a few pointers on how to do it with the above surface charge density.

Thanks in advance guys........
