I want to do a webpage of my own on the x^4 potential. What is your webpage url?

I need an algorithm to find any or all eigenvalues for the x^4 potential to as many digits of precision as I want, then I can start figuring out what happens to the sin wave outside the bounds for x where it is going haywire. Right now I don't know if it is because of not having found an exact enough value for the eigenvalues or if it is because of insufficient terms in my series.

Well of course it does -- that was my point. Try the your method on
the x^2 oscillator and see if your method works where you know the
answer. I'm dubious that your graphical method will be all that good.
See my webpage for a picture of the time-dependent QM x^2 oscillator.
