Sequences and Series Plotter
An interactive and visually appealing mathlet for exploring convergence, divergence, and distribution of terms of sequences and series of constants.
The Method of Characteristics & Conservation Laws
This article describes the Method of Characteristics for solving first-order PDE's and applies the method to solve nonlinear hyperbolic conservation laws.
How to Submit an Article to Loci
A brief outline of policies for submission of articles to Loci.
Birthday Problem & Class Phenotypic Probabilities
A Biological ESTEEM module in the Genetics Category. This Excel workbook as two related applications, the Birthday Problem and Class Phenotypic Probabilities.
How to Cite
Instructions for citing articles, modules, and mathlets in JOMA
Interactive Supplements to Rick's Tricky Six Puzzle
Three applets allow you to interact with the puzzle described in the April 2009 Mathematics Magazine article by Alex Fink and Richard Guy.
GeoPhyl
A Biological ESTEEM module in the Phylogenetics Category. This workbook allows students to explore evolution over space and time using published data on the invasive plant Tamarix (salt cedar).
Maplets for the Area of the Unit Circle

This teaching module uses Maple Maplets to illustrate several different methods of estimating the area of the unit circle.

Exponential Functions
A module to explore the properties of exponential functions through models of growth and decay
CalcPlot3D NOT
This dynamic Java applet allows the user to simultaneously plot multiple 3D surfaces, space curves, parametric surfaces, vector fields, contour plots, and more in a freely rotatable graph. This tool is intended as a dynamic visualization and exploration environment for multivariable calculus. Use it to illustrate the geometric relationships of many of the concepts of multivariable calculus, including dot and cross products, velocity and acceleration vectors for motion in the plane and in space, the TNB-frame, the osculating circle and curvature, surfaces, contour plots and level surfaces, partial derivatives, gradient vectors and gradient fields, Lagrange multiplier optimization, double integrals as volume, defining the limits of integration for double and triple integrals, parametric surfaces, vector fields, line integrals, and more.
