1. The problem statement, all variables and given/known data Consider the time-dependent Schrodinger equation for a free particle in two spatial dimensions Using the method of separation of variables, determine the wave function ψ(x,y,t) 2. Relevant equations 3. The attempt at a solution Not sure how to do the separation here since it is a function of 3 variables, I'm inclined to think that Ψ(x,y,t) = f(x) g(y) j(t) can be assumed, hence substitute it in the equation and separate. Is it correct to assume that?
