## Homework Statement

Calculate the expectation value for the z component of angular momentum (operator is (h/i)(d/dx)) for the function sinx*e^(ix).

## Homework Equations

I think the only one relevant is the expectation value:

<a> = integral[psi*(a)psi] / integral[psi*psi] where psi* is the complex conjugate and a is the operator (in this case, the operator of the z component of angular momentum).

## The Attempt at a Solution

I don't really know how to begin this one, but I assume that you have to find the <a> equation where <a> is the expectation value. In that case, do you just take the integral of psi*(a)psi over the integral of psi*psi? In this case, psi = sinx*e^(ix)
