Homework Statement
One dimensional harmonic oscillator is at the beginning in state with wavefunction ##\psi (x,0)=Aexp(-\frac{(x-x_0)^2}{2a^2})exp(\frac{ip_0x}{\hbar })##.
What is the expected value of full energy?
Homework Equations
##<E>=<\psi ^{*}|H|\psi >=\sum \left | C_n \right |^2E_n##
The Attempt at a Solution
So I tried to find ##C_n=\int_{-\infty }^{\infty }A^2exp(-\frac{(x-x_0)^2}{a^2})dx##
But I have no idea on what to do with this integral.. Whatever I do, i keep getting this integral. What can i do here?
