I should have said this but anyway, the Shrodinger's equation solution for the x^4 potential involves the bessel_i functions and one of them is
A*bessel_i(-1/6,x^3/B)*sqrt(x) for Energy = 0
which is why I brought this up.

What I have done is redefine bessel_i(n,x) in terms of it power series to evaluate for -1/6 but I do not want to have to evaluate it that way.
Also, the Shrodinger's eq for the x^4 potential can be solved in Mathematica for the special case where Energy = 0. Maxima can't do that it seems, but I was trying to find a way to work around that and do it in Maxima.

Maxima cannot evaluate bessel_i(-1/6,1). It seems like it does not evaluate for any negative first argument. Is there a work around for this?
