## Homework Statement

If <x> and <p> are the expectation values of x and p formed with the wave-function of a one-dimensional system, show that the expectation value of x and p formed with the wave-function vanishes. The wavefunction is:

[tex]\phi(x)=exp(-\frac{i}{h}\langle p\rangle x)\psi(x+\langle x\rangle)[/tex]Basically I don't know how to start this problem. Do I plug in the integral forms of the expectation values into the exponential and distribute the psi over x and [tex]\langle x\rangle[/tex]?
