Within the framework of quantum mechanics, show that the following are Hermitian operators:
b) [tex]L=-i\hbar r\times\bigtriangledown[/tex]
Hint: In Cartesian form L is a linear combination of noncommuting Hermitian operators.
The Attempt at a Solution
I understand that a Hermitian operator is self-adjoint, and that it's eigenvalues are real, but as far as proving it, I'm not exactly sure how to use the formula above to do that.
