I know what it does, I know sort of how it works. What I cannot find is a simple example of how to use the hazy mathmatical jargon of f(x,t)?! in a real problem.
My question, straight to the point;
Euler looks like, so:
acceleration = f/m;
velocity += acceleration * dt;
position += velocity * dt;
Now how does that work in RK 2 or 4?
I''ve tried all sorts of crazy things and nothing wants to work.
I figured that since k1 = f''(x, t) that it is saying "k1 is the acceleration at point X0, T0. After that I get completely lost.
