comment How to make Runge-Kutta for solving nonlinear ODE system in Mathematica
@George: Finally, I keep telling you to try to reduce your problems down to the bare minimum. This is both good for you and for the forum. The act of isolating your sticking point will normally help you solve it. And if you're still stuck, you can post a nice clear question that other people can work on without having to dig through the muck for you.

comment How to make Runge-Kutta for solving nonlinear ODE system in Mathematica
@George: You really should learn how to use Mathematica for the simple examples before you try to apply it to your real work. I've been helping you since August and neither your ability to program nor your ability to ask clear questions on a forum has increased. People want to help, but are not going to do ALL of your work for you. Make your questions either interesting or short. Long, messy, stupid and frustrating questions will get downvoted or ignored.

comment Inverse of the polylogarithm
@jspecter: $\text{Li}_n^{-1}(z) \approx z-2^{-n} z^2+(2^{1-2 n}-3^{-n}) z^3 + \dots$... but is the general coefficient known in closed form? Can it be summed as, e.g., a hypergeometric?

@J.M.: That should read f[0] = 1; f[n_Integer?Positive] := f[n] = n f[n-1]

comment If $f(n) + (n+1)^2 = f(n+1)$ then what is $f\phantom{|}$?
+1: Of course the general solution for arbitrary $f(0)=c$ is not too difficult.

comment What is a good language to develop in for simple, yet customizable math programs?
Also, sage has a web-based notebook interface and dynamic content: ineract. This makes it good for classroom work.

Oh... you're missing a squared in your first sum
