Greetings,(adsbygoogle = window.adsbygoogle || []).push({});

As I am in vacation now there is no way to ask my teacher so I will resort to this forum, I searched and didn't find it on the forum ( hope I haven't skipped anything ) so here goes my question:

For the Runge-Kutta integration methods, I am really puzzled as to what the 'f' function is, for example one of the variables for the x_{n+1}is f (tn + h⁄2, xn + h⁄2 b), what exactly does the 'f' signify ?

Thank you in advance,

Parvulescu Cosmin
