With Double Pendulum application you will be able to simulate problem a pendulum hanging from another pendulum situation. It's easy to make one, but it's a pretty ferociously difficult mathematical problem, by most peoples' standards. To even set up the relevant highly non-linear dual differential equations requires the formidable somewhat abstract mathematical machinery of Lagrangian Dynamics and Generalised Co-Ordinates. Surprisingly though, the program to solve these equations numerically using the improved Euler method is fairly short and simple (once I ironed out my algebraic errors, which are very easy to make). Program keeps on running until you stop it. The Total Energy (Kinetic + Potential) should remain unchanged throughout the motion, but as time progresses the error in the calculations very slowly accumulates.
