Problem 2.9

For the wave function in Example 2.2, find the expectation value of
H, at time t=0, the “old fashioned” way:

$\langle H \rangle = \int \Psi (x,0)^* \hat{H} \Psi(x,0) dx$

Compare the result we got in Example 2.3. Note: Because $\langle H \rangle$ is independent of time, there is no loss of generality in using t=0.
