3. [3] The physics is like in the previous question (i.e. you have a particle confined to a ring around the z-axis), but this time at time t = 0, the state is |4(t = 0)) = |-1) + - 12). Find the probability density as a function of space and time. To be explicit: that means find the magnitude squared of the spatial wave function, i.e. compute hu (p, t) |2.
