Okay, I have no idea where to even begin on this problem. I get the feeling it's very easy and I'm just overlooking something simple, but if someone could give me a push in the right direction I'd be super appreciative. Thanks in advance!

Prove that <K> = <V(x)> = E_{v}/2 for a one-dimensional harmonic oscillator for v = 0 and v = 1.

Any insight would be greatly appreciated. Thanks again!
