On March 8 in Class I wrote that, for a particle in an innite square well (with V(a) = 0 for 0 g a: g L and V > oo otherwise), the expectation value of 3:2 in quantum state 71 is given as (552%; 2 L2(% ring ). Derive this result, using the wave functions tbn(x) as given given in Eq. 6.34 (same as in class notes)
