What Determines Even and Odd Functions in Quantum Equations?

[opeth_35]

hi,

I want to ask you something about the equation in the quantum which is called like EVEN and ODD function and we are solving according to this values and when the functions have been even and odd, we re saying that is equal to zero like that..

I am wondering actually, We are saying odd and even function according to what? I have not figured it out? Is there someone to know how this happens ?

ALSO, You can see example what I am talking about on the addition page..
