Homework Statement
normalize the wave function [tex]\Psi(x)= Acos(\Pi*x/a)[/tex] to show that A=[tex]\sqrt{2/a}[/tex]
The Attempt at a Solution
i don't know how to get that answer as all i can tell, normalizing gives:
[tex]-A^{2}pi^{2}2x/a^{2} * sin (pix/a)[/tex]
However this does not give the right answer for A
Any help pointing out what I've missed would be great.
