After setting up Laplace's equation in spherical coordinates and separating the variables, it is not clear to me why the constants are put in the form of l(l+1) and why m runs from -l to l. Could anyone please help me ununderstand, or better yet, point me to a source that explains the entire process of separating Laplace's equation in spherical coordinates in detail? I have not been able to find anything on the internet whi h clarifies these points. It merely states them as facts.(adsbygoogle = window.adsbygoogle || []).push({});
