## Main Question or Discussion Point

Can somebody explain how you get:

<p

.....

= i

Conceptually, I am having a problem with how the inner product is formed when a derivative is involved (i.e. the ..... steps)

<p

_{m}|p|p_{n}> = (1/2π)∫e^{-ipmx}/__h__(-i__h__∂/∂x) e^{ipnx}/__h__dx.....

= i

__h__∂δ(p_{m}- p_{n})/∂xConceptually, I am having a problem with how the inner product is formed when a derivative is involved (i.e. the ..... steps)
