Oh I see! ##\Psi## is indeed symmetric/even around ##x=L/2##. So is it then a valid argument to say that only even eigenstates contribute to even functions?
Homework Statement
For an infinite potential well of length [0 ; L], I am asked to write the following function ##\Psi## (at t=0) as a superposition of eigenstates (##\psi_n##):
$$\Psi (x, t=0)=Ax(L-x) $$
for ## 0<x<L##, and ##0## everywhere else.
The attempt at a solution
I have first...
Hi everyone, first off i'd like to thank you all for maintaining this awesome forum, seems really cool :D
I wasn't sure whether this should be in the homework forums or not, but since I'm not asking for any solution of some sorts, i decided to post here.
