Homework Statement


u''-bc (x^m) u =0

Homework Equations


How can I write the general solution in terms of Bessel function?

The Attempt at a Solution



This form is a transformed vresion of y'+by^2=cx^m with dummy variable by=1/u *du/dx

I'm curious why you would go to the trouble of transforming your original DE when you can solve it directly. It's just a constant coefficient DE with a non-homogeneous polynomial term.

it was y'+by^2=cx^m ,Iforgot to type the y squared power
 
Here is what Maple gives, for what it's worth:

Maple worksheet showing the input diff(y(x),x)+b*y(x)^2=c*x^m and the dsolve output, a long expression for y(x) written with BesselJ and BesselY terms of argument 2 sqrt(-bc) x^((m/2)+1)/(m+2).
