Hénon-Heiles Equation
The Hénon-Heiles equation is a nonlinear nonintegrable Hamiltonian system with
where the potential energy function is defined by the polar equation

The total energy of the system is then given by

which is conserved during motion.
Integrating the above coupled ordinary differential equations from an arbitrary starting point with 
and 
gives the motion illustrated above.
Surfaces of section are illustrated above for various initial energies
