Hi, so I'm trying to solve Laplace's equation by separation of variables, and there's a basic step I'm not understanding with regards to the product rule.
Given
A product rule (i think) is taken to make the first term easier to deal with and we get
I'm just having trouble understanding what the derivatives of f and g are. And am I correct in saying that f = 1/r*partial wrt r
g = r * partial phi wrt r
Thank you
