Parametric for Linux

Parametric is an utility for the study of forced oscillations of the modified Duffing pendulum : This program allows an numerical exploration of the phase space (x,dx/dt). This exploration is made more convenient with the use of the mouse and the graphical output. This convenience yield to an easiEST and more intuitive approach to this standard problem of classical mechanic. With this tool, one can grasp some aspects of the Hamiltonian chaos. (This system is not dissipativ).
