## Homework Statement

Folks, I am looking at a past exam question regarding the Harmonic Oscillator. The question ask

'Justify that the ground state of a harmonic oscillator

[tex]a_\psi_0=0[/tex] equation 2.58 on page 45 of griffiths.

THis was not covered in my notes. Any ideas how to justify this expression?

Thanks

Eddie

PS, how come [tex] [/tex] isnt working for me?
