Hello,

Consider the power series expansion of the solution (in any equation)

Then

etc...

Then find a recursive relation between and (or possibly , for the last equation)

See here for an example : http://www.mathhelpforum.com/math-he...s-problem.html (take care of the steps, that's all) - Jul 29th 2009, 12:44 PMdiddledabbleWhat about with initial values
