Quantum Harmonic Oscillator Part 2

We solve the differential equation for the Quantum Harmonic Oscillator, using various "tricks" and Hermite Polynomials.

Looks like there is a sign error right off the bat. You change the left hand side's signs but leave the right had side's sign the same. It should have flipped as well.

great video ! At the end I think you missed a ^2 in h bar when showing that z = sqrt (mk/h). It should be z = sqrt (mk/h^2)

Your lectures are helping me a lot. Thanks!!

Can you please explain why the wave function \phi_1 for the first excited state is 0 at x=0, video time 7:25

Thank you sir!
It was really helpful... :)

jesus that was fast, quite hard to follow if you try to take notes, if you just watch it makes sense though.

The differential equation in 2:05 should be d^2phi/dy^2=(y^2+k)phi...you did a sign mistake in last video
