Hello,
on the Wikipedia page for a general example of the Ehrenfest theorem, they note that <dp/dt> and <dx/dt> because the operators p and x have no explicit time dependence. But we have
<dp/dt> = <ψ | (d/dt)pψ>
<dx/dt> = <ψ | (d/dt)xψ>
and I can't seem to prove that these inner products (which become integrals) go to 0. I'm definitely misunderstanding something here, so any help is much appreciated.
Thanks!
