first post! but for bad reasons lol(adsbygoogle = window.adsbygoogle || []).push({});

Im trying to find <x> and <p> for the nth stationary state of the harmonic potential: V(x)=(1/2)mw^2x^2

i solved for x: x=sqrt(h/2mw)((a+)+(a-))

so <x> integral of si x ((a+)+(a-)) x si.

therefor the integral of si(n+1) x si + si(n-1) x si.

si(n+1) x si as far as I know is always 0 so this would mean <x>=0?

this same convention would be used for <p>.

sorry for the sloppy work but I'm pretty sure <x>, and <p> shouldnt = 0

please help, and thanks for the posts!
