Solve the eigenvalue problem(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\frac{d^2 \phi}{dx^2} = -\lambda \phi[/tex]

subject to

[tex]\phi(0) = \phi(2\pi)[/tex]

and

[tex] \frac{d \phi}{dx} (0) = \frac{d \phi}{dx} (2 \pi).[/tex]

I had the solution already, but am looking for a much simpler way, if any.

EDIT:

Sorry that I accidentally posted this twice; I meant to edit the post, but not sure why the edited post becomes a new one...
