Apart from the usual integral method, are there any other ways to find expectation value of momentum? I know one way is by using ehrenfest theorem, relating it time derivative of expectation value of position operator.
Even using the uncertainty principle, we might get it if we know the uncertainty in position but not the exact value as we might get only the lower bound of it.
so, if any other ways, please do share!
