Testing Java Applets
This collection of Java applets comes from a mathematics professor at Kennesaw State University. Most of the utilities are used to demonstrate graphical representations of different kinds of equations. For example, the Quadratic Functions section contains applets that let the user change the values of the equation's parameters, and the graph is updated to show how the underlying function changes. There are also applets that help users visualize the processes of differentiation and integration, a
