Homework Statement
I was reading this textbook:
https://books.google.com/books?id=s...10#v=onepage&q=orbit center operators&f=false
Homework Equations
In the equation of the page (unlabeled), we have
$$
\left[A_x\frac{\partial}{\partial y} - \frac{\partial}{\partial y}A_x + \frac{\partial}{\partial x}A_y - A_y\frac{\partial}{\partial x}\right]\psi(x)\\
= \left[- \frac{\partial A_x}{\partial y}+ \frac{\partial A_y}{\partial x}\right]\psi(x)
$$
The Attempt at a Solution
Why do the first and fourth terms cancel out? Is it to do with the circular motion of the charged particle in the magnetic field?
