Consider a particle in a box of length L with one end coinciding with the origin. Consider the initial state to be given by the wavefunction:
(x, 0) = A sin 2nrx/L for 0 < x < L/2 and (x, 0) = 0 for x > L/2. Normalize this wavefunction. Compute the time evolution of this
system. Find the probability of measuring E; at some time t.
