A Biological ESTEEM module in the Developmental Biology Category. This Excel workbook illustrates a number of allometric equations in animal growth.

This is an article describing the author's experiences using the Duke Connected Curriculum materials

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 applet encourages students to use the mathematics of the motion of a projectile to choose angle and velocity necessary to hit a roving target. The source code is available from the link within the Sharing Area of the Flash Forum.

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.

This article explores the symmetry method in elementary differential equations, which uses the invariance of the equation under certain transformations to create a coordinate system in which the equation greatly simplifies.

This ESTEEM module in the Biometrics Category leads the user through several different methodologies for applying Bayesian probabilities to real life examples and problems.

This Java applet plots up to 10 functions simultaneously with zoom and trace features. It can be used to study properties of functions or approximate solutions to equations. The syntax for entering the functions is given on the accompanying web page.

This module a standard model of population growth in a constrained environment.
