Relevant equations http://img199.imageshack.us/img199/484/232ag.jpg [Broken] sorry about the insert pictures, i dont know how to type up the eqns easily 3. The attempt at a solution Now I know that outside the box the schrodinger equation should give 0 right. I'm just not sure how to go about (a) and (b). (c) The expectation value is pretty straightforward in that you just evalutate <psi|omega|psi>/<psi|psi> with the boundaries from 0 to L and we know the denominator here is 1 since it's normalized.
