# Hermitian problem

1. The problem statement, all variables and given/known data

A and B are noncommuting quantum mechanical operators:
AB - BA = iC

Show that C is Hermitian. Assume all the appropriate boundary conditions are satisfied.

I do not understand how to show this. I isolated C as:

C = i(BA-AB)

..and I want to show that C is Hermitian showing:
$$\int\stackrel{a}{b}\psi^{*}C\psi d\tau$$
is equal to:
$$\int\stackrel{a}{b}\psi(C\psi)^{*} d\tau$$

Can someone help? Thanks!
