Homework Help: Bounday-Value Problem: Eigenvalue and Eigenfunctions

  1. Jul 15, 2008 #1
    1. The problem statement, all variables and given/known data
    This is the original question:

    (Hint: Let t=[tex]x^{3}+x[/tex])

    2. The attempt at a solution
    This might be all wrong, but this is all I can think of

    so [tex]\frac{d^{2}y}{dx^{2}}-\frac{6x}{\frac{dt}{dx}}\frac{dy}{dx}+\lambda(\frac{dt}{dx})^{2}y=0[/tex]

    After this, I do not know how to proceed to eliminate [tex]d^{2}y/dx^{2}[/tex], much less what else to do. Help!

    Thank you very much for your time,

    nevermind. Im in Miami Florida. But I got the same question as you at the same time. One hell of a coincidence. Let me know if you find the answer, and you can check my thread too, I got the same question posted on there.
