JOde - A Java Applet for Studying Ordinary Differential Equations

The following pages set up the JOde Applet to perform the following tasks

• Slope fields and solutions of equations of the form y'=f(x,y)
• Direction fields and solutions of equations of systems of equations of form x'=f(x,y), y'=g(x,y)
• Solutions of equations of systems of equations of form x'=f(x,y,z), y'=g(x,y,z), z'=h(x,y,z)
• An example from population dynamics - Elks, Coyotes and Wolves in Yellowstone Park
• An example of a circuit
• A simply model of sunami
• The two-body problem
• A solution verifier which can be used to compare numerical solutions to exact and approximate formulas. In particular, can be used to test series solutions.
• A solution verifier for systems of 2 equations.
• Limit cycle for the Van der Pol equation
