Morning All. I have a system I am completely stuck on. Differential equation of function composition of two variables. I need find a numerical solution of this system, like f(x(t),y(t)) = ... Any Help Regards

Is this a stiff problem in the region of phase space you are interested in? If not, I would just use RungeKutta. If you aren't familiar with it there is a link below but in a nutshell, its a weighted average of particular Euler steps. https://en.wikipedia.org/wiki/Runge%...3Kutta_methods Hope this helps.

oh yeah and if the problem is stiff, Taylor expand.
