We highlight five pages written in XHTML with links to SVG files that produce animations illustrating calculus concepts such as the sign of the derivative, inflection points, conic sections, area between two curves, and multivariable functions.
This suite of five interactive applets (written with GeoGebra) allows exploration of definitions and theorems commonly presented in first-year analysis courses. Topics include sequence convergence, continuity at a point, the Mean Value theorem, Taylor series, and Riemann sums. Included with each applet is a pair of activities: one for becoming comfortable using the applet, and one for using the applet to explore the associated topic in depth.

This article presents a fresh look at an age-old calculus optimization problem, the 'box problem.' (Also includes a Student Module condensed from the article.)

This is a student module for the article, which presents a fresh look at an age-old calculus optimization problem, the 'box problem.'

This article describes methods for creating interactive math materials using the HTML5 canvaselement.

This article introduces and reviews the 'Easy Java Simulations' software environment for developing math explorations as interactive Java applets.

This article looks at several geometric, straightedge-and-compass constructions for trisecting a line segment, comparing them based on the numbers of lines or circles required for the construction.

This interactive page allows readers to construct a Kuratowski 14-Set on the real line by selecting from among ten checkboxes, each representing a given set of real numbers.

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.

This tutorial shows the details of composing the POV-Ray code necessary to generate the image of a dodecahedron, and to animate rotating the dodecahedron.
