This is the problem I'm working on: http://i.imgur.com/PBMFG.png

I'm very behind with normal modes and waves, and I need to figure out how to do this sort of question in time for my exams, so I'm hoping that you guys will be able to help me see how this can be answered.

I've answered the first part, deriving he wave equation, but for the second part I'm feeling very lost. Can someone give me a hint or nudge in the right direction for how to get started with it?

I certainly don't know how to answer that, but seeing those second O.D.E's makes me think you might have better luck not posting this in introductory physics.

Oh, I see! Thanks for the advice, I'll try advanced physics.
