I think it is a waste of time to try understanding sample codes written by other people. In stead, you should write your own code. Yeah, it may take more time but, it will be educatinal for you.

thanks for for help. I've programmed a simple runge-kutta function, it's not a good approximation but according to my lecturer it's good enough for this project

iamthwee, DaniWeb actually has built-in Tex functionality by using the tex bbcode. There is no need to hotlink tex from an image upload service
iamthwee=x^2

Use Gnu Scientific library, GSL.
Also there exist many free software numerical packages, e.g. ROOT (http://root.cern.ch)
