I am pretty sure that I'm doing this right but the integral for normalization seems impossible. Here is the question:
Normalize this wave function.
psi(x,t)=Axe^(-sqrt(km)/2h)*x^2))*e^(-i(3/2)(sqrt(k/m)*t)
for -infinity<x<+infinity where k and A are constants and m is given.
I used int(psi(x,t)psi*(x,t)dx)=1 and have arrived at the following integral, which I (nor online integrators) can't clearly do:
int(A^2*x^2*e^[(-sprt(km)/h)*x^2]=1
According to the back of the book, the answer is [sqrt(2)/pi^(1/4)][km/h^2]^(3/8). Any help would be appreciated!
