I am working on the derivation of the angular momentum squared operator (in quantum mech.) and there is one step that I don't see how it works. I'm not sure that this is the right place to post it, but since this is a strictly mathematical question, I figured I would post it here. The equivalence is as follows:
(cotθ)(∂/∂θ) + (∂/∂θ)2 = (cscθ)(∂/∂θ)[(sinθ)(∂/∂θ)]
I don't see how to go from one to the other
(cotθ)(∂/∂θ) + (∂/∂θ)2 = (cscθ)(∂/∂θ)[(sinθ)(∂/∂θ)]
I don't see how to go from one to the other
