Thanks for responding. I only entered those initial values to test that my RK method was working. However, I will have to enter large values of θ, and the small amplitude approximation will no longer be accurate. I happened to come across the following website...

For my RK method I initialised the variables as follows: θ = 0.1 ω = 0 dt = 0.04 (time step) However, I have to investigate the dynamics of the pendulum at progressively larger amplitudes.

1. The problem statement Hi everyone, I'm currently working on an assignment that involves modelling a non-linear pendulum in C. I have to investigate the dynamics of a simple non-linear pendulum all the way up to a chaotic damped, driven situation. However, I'm completely baffled as to how...
