I have a question regarding the expectation value of particle:(adsbygoogle = window.adsbygoogle || []).push({});

"Obtain an expression for the expectation value [tex]<p_{x}^n>[/tex] where n is 1,2,3... of a particle in an infinite box (U = infinity for x<0 and x>L; U=0 for 0<x<L) which is in an eigenstate of the energy."

That is the question word for word.

Now, I have basically no idea where to even begin with this. The Prof zipped through it just so he can say he covered the material during the final class. Now we have to answer questions and I am lost.

I know no one likes to give answers without seeing work, but I simply don't know what to do.

Any help with a push in the right direction would be great.

Thanks.
