Homework Statement
A) Show that <x>=<p>=0
hint: use orthogonality
B) Use the raising and lowering operators to evaluate an expression for < x2 >
Homework Equations
Also A- and A+ will definitely come in handy
The Attempt at a Solution
I tried setting up the equations for <x> and <p> but I don't know how the operators are meant to be used in this scenario. I think that the integral is meant to be set up as ∫eq1*xop*the general equation for ψn for a harmonic oscillator, however whatever I do I can't get the math to come out to 0 in the end for either.
