Mathematica notebook from handout: Section 1.7 Problem 2b.
Marek Rychlik's suite of applets for solving differential equations is JOde.
Here are some Mathematica notebooks for the 2 Degree of Freedom Hamiltonian System that we
studied. First open and run this one to define
some functions, and then open this one and run a
cell at a time to see some results.
Hamiltonian systems with two degrees of freedom are related to the
Standard Map.
