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 twobody 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.
