## Homework Statement

Prove the operator d/dx is hermitian

## Homework Equations

I know that an operator is hermitian if it satisfies the equation : <m|Ω|n> = <n|Ω|m>*

## The Attempt at a Solution

Forgive the lack of latex , I have know idea how to use it and find it baffling.

the intergral of (fm* d/dx fn) dx = the intergral of fm* d fn

={fm* fn - the intergral of fn d fm*} between the limits x=infinity and - infinity.

This is where i get stuck. I just dont know where to go from here, like i said sorry for the lack of latex usage :(.

Thanks for the help :D
