1. The problem statement, all variables and given/known data p: momentum x: position t: time h_bar: planck's constant Ψ: wave function 2. Relevant equations 3. The attempt at a solution I've posted a link to pictures. http://imgur.com/a/TKvUu [Broken] I'm not vera good at using LaTex yet :( So I've shown that the wave equation satisfied the schrödinger equation, but I'm not sure how to find which A(p) will also satisfy the schrodinger equation? Any pointers?
