Quantum Mechanics postulate
Hi I am new here and also new to QM.
I have encountered a problem about postulate 2 which is the superposition principle. Basically I understand the concept. However, when it comes to real question, I get stuck and can't proceed. Could anyone enlightens me how to get started with the problem below?
A psi(x) = [psi(x)]^2
Is A a linear operator? Is A a Hermitian?

Heh, I found the way to solve it already!

BTW: You should start using the notation [tex](A\psi )(x)[/tex] instead of [tex]A\,\psi(x)[/tex]. It will help you to understand better the mathematical operations involved.
[tex](A\psi )(x)[/tex] reads: the value of the function [tex]A\psi[/tex] at the point x.
Operators act on functions (as objects) and not on values of these functions (numbers).
