# Homework Help: Normalizing a wavefunction

1. Jan 30, 2016

### zahra95

1. The problem statement, all variables and given/known data
the wavefunction

where < | > =

. I want to normalize it and find constant normalization A. A is real number.

2. Relevant equations

3. The attempt at a solution
I know that for normalizing the wave function

but what happen for sigma? can I remove it from equation?

You can't just ignore the sigma! First, can you find an expression for $||\phi||^2$?

I think the equation is :

because < | > = is it correct? i'm not sure!
but what I do after that?

That's obviously not right. If you're stuck with an infinite sum, try a simple sum and see what happens. Try:
$\phi = A(\phi_0 + \frac{\phi_1}{3^4})$

and

for n = 0,1
= A^2(1+1/3^8 + 1/5^8 + 1/7^8 + ... )
then it is true that = A^2(1/(2n+1)^8) isn't it?
