i need the derivation of orthogonal properties of associated laguerre polynomial (with intermediate steps). someone please tell me where can i get it (for easy understanding).

I'm pretty sure you just appeal to usual Sturm Liouville Orthogonality, just work out the weight function which I think is e^(-x) but haven't looked at in a while.
