Hi everyone, I am having issues understanding how Legendre functions work especially the recursion and what the subscripts mean in general. I am attempting to make a program to compute the legendre functions Pnm(cos(theta)) and the normalized version and then verifying it by plotting 4 normalized legendre functions.
I don't understand what to do with these equations to get to what I'm attempting to do they just confuse me to no end.

I'm pretty sure I have to make a function to start with the original equation and then recursively go down. What do the subscripted n/m mean I'm confused on that as well xD
