Here are some numerical simulations of nonlinear and linear oscillators:

• Right-click here to save a Maple worksheet with the study of nonlinear harmonic oscillators, and their linear counterparts.
• Click here for a Java-based simulation of a nonlinear harmonic oscillator. The Java scripts on this page were kindly provided to the Web community by www.myphysicslab.com
• And now two chaotic examples: Java simulations of a double pendulum, and a harmonically forced damped pendulum
