2.14, 2.37

For a harmonic oscillator, calculate < x > and < p > for the mixed state 2+3 . (Where 2+3 means the state that is an equal (normailzed) admixture of Psi sub 2 and Psi sub 3.)

For a harmonic oscillator, calculate < p**2 > for:
a) the mixed state 2+3. Is this time dependent?
b) the mixed state 2+4. Is this time dependent?
