The pages contain a collection of applets designed for teaching Calculus, two packages of java classes used for writing such applets, and full documentation of the packages and their use.
Source code is provided for all the sample applets in the documentation below.
Above is a screen shot of one of the applets. This one is for experimenting on Newton's method in one dimension and finding basins of attraction. The depth of the line indicates how many steps it took to converge to the specified accuracy. For example, the badge up above the graph gives the coordinates of the cursor. Further instructions on the use of these applets is provided on the individual pages containing them.
