Homework Statement
So I was able to find a problem that was kind of similar to a homework problem that I am working on. Unfortunately, I'm not quite sure what is going on partially within the problem.
In the problem they state that [itex]\phi[/itex]=[itex]\phi[/itex]*, but it does not state why. I was wondering if someone could explain this to me?
Also, later on in the problem e[itex]^{-i\phi}[/itex]e[itex]^{i\phi}[/itex]+e[itex]^{i\phi}[/itex]e[itex]^{-i\phi}[/itex] cancels out along with the 1/2i. I'm not quite sure how this happened either. I have tried to review the euler's equation to understand where this comes from because I'm supposing it is being canceled out based on its properties.
I have attached the proof to this forum.
I would greatly appreciate some help because the problem I am working on involves proving that the integral of the current density over a surface is equal to the momentum operator/m. I understand conceptually what this means but I need a push in the write direction with the math behind it.
