This aplet takes a vector problem involving two objects having
an initial position and velocity and analyses it as 'closest
approach' style problem. A test tool rather than a
teaching tool.

Curves Collection
This collection of mathematical curves was
originally hosted on Jim Donnelly's page but has been shifted to
mine now that Jim has moved on to other interests. These ApLets allow the user
to explore interesting mathematical curves. Includes Cardiods,
Catenaries, Astroids and Lissajous curves. Excellent fun!
Note: Currently only the HP38G versions
are available as aplets but the equations are given on the page
and can be entered manually on an HP39G.

First 50, The
This is a collection of small programs you can type in
yourself or download. They perform a multitude of small
tasks, some that are so easy you'll wonder why I wrote a program
for them, some that are really cool. For FAR more information click here.

Quadratic Focus & Directrix
This is an aplet which lets you explore the relationship
between the focus and the directrix of a quadratic
equation/graph.

Inequalites
This is a copy of the function aplet with the additional
ability to graph inequalities (linear/non-linear) for F1, F2 and
F3(X). These can be overlaid to show intersections or
unions. More Information

Transformer
This is an easy adaption of the Parametric aplet which allows
the student to investigate geometric transformations using 2x2
matrices. It is easy to create it
yourself instead of downloading it. It is a fantastic
teaching tool - my class deduced all the basic 2x2
transformation matrices for themselves in less than an hour. More Information
