This utility uses the free Flash player plug-in resident in most browsers to provide the student with interactive examples and practice problems to aid in learning about spherical coordinates.

An article on the use of technology to stimulate mathematical thinking even by the least likely students

This mathlet simulates a predator-prey system of foxes and rabbits over time.

This paper uses graphics and animations to illustrate how to construct root and weight diagrams for Lie algebras, and how the root and weight diagrams can be used to identify subalgebras.

A Biological ESTEEM module from the Ecology Category. This worksheet compares user-input growth data with predictions under linear, exponential, and logistic models of growth.
A preparatory module for problem-solving in physics and calculus that covers systems of units, dimensional analysis, significant figures, estimation, and orders of magnitude

This gallery of images and animations shows many examples of how the POVray ray-tracing software can be used to display examples in three-dimensional geometry.

Part of the MathDL OSSLET Collection, this flexible and easily-used applet can be used to investigate and animate up to three functions involving up to four parameters.

Marden's Theorem concerns the relative positions of the roots of a cubic polynomial and those of its derivative. This article gives a proof of Marden's theorem, along with dynamic geometry animations and some of the history of the result.

A Developers' Area article about reuse and interoperability of mathematical tools.
