## Time-dependent Superposition and Expectation Values: Infinite
Square Well

#### (Illustration)

The superposition shown is an equal mix of the two states n_{1
}and n_{2 }for the infinite square well, Y_{n1n2}(x,t)=(1/2)^{-1/2
}[f_{n1} (x,t) + f_{n2}
(x,t)]. Change the state and watch DxDp---written
as dxdp---measured in hbar, change with time.

Look at what happens to the wave function and the expectation
values when both n_{1} and n_{2} are even or odd.
