## Homework Statement

Use the ground-state wave function of the simple harmonic oscillator to find: Xav, (X^2)av and deltaX. Use the normalization constant A= (m*omegao/(h_bar*pi))^1/4.

## Homework Equations

deltaX=sqrt((X^2)av-(Xav)^2)

wavefunc=A*e^(-ax^2) ?

## The Attempt at a Solution

I'm not sure if I'm on the right path, but I started out by plugging in A and doing the integral of the wavefunction. My question is... does doing this give me Xav? If not, how would I go about solving this problem?
