Math in Society is a free, open textbook. This book is a survey of contemporary mathematical topics, most non-algebraic, appropriate for a college-level topics course for liberal arts majors.

IMathAS is an Internet Mathematics Assessment System. In essence, it is a very light Course Management System (CMS), most similar to (and inspired by) WebWork and WIMS, and similar to publisher-produced systems like iLrn, MathXL, etc. IMathAS is written in PHP, and uses MySQL. IMathAS is released under the GPL

These graphing projects consist of 3D, 2D, and ODE graphing applets, built off the incredible JavaView API. They are written in Java. Please note that while my source is being released under the GPL, the JavaView API is not GPL'd and is not open-source. Please view the copyright notice from the creators of JavaView. Running the Grapher on your local machine also requires a free registration of JavaView

Use the Graphers

If you just wish to put the grapher applets on your website, you do not need the source code. You can download the compiled .jar files from the grapher page. View Source on the grapher pages to see how to embed the applet in an HTML file.

This project is a porting of the HTMLArea AsciiMath/AsciiSvg plugins (see below) to work with the TinyMCE editor. These plugins require no modification to the TinyMCE editor, and provides image-based fallback for math and graph when the browser does not support MathML and/or SVG.

This set of scripts provide functions for converting ASCIIMath calculator style notation to TeX strings, and provide drop-in replacements for ASCIIMathML.js providing serverside image rendering when the client does not support MathML.

Also available are a server-side ASCIIMath to TeX script, and a Moodle filter for rendering ASCIIMath notation as images

These scripts are derived from Peter Jipsen's ASCIIMathML script.

This project is a super-simple file and image browser for the TinyMCE editor using Amazon S3 for file storage. Code for multi-user systems can be added so each user has their own file storage. Requires PHP5.

A joint project with Peter Jipsen of Chapman University, these plugins use Peter's incredible ASCIIsvg and ASCIIMathML scripts to allow for live editing of math and graphs in a web page text editor.

These plugins required substantial modification to the HTMLArea web-based editor. For that reason, this distribution includes a pared-down copy of the HTMLArea editor distribution with the plugins installed, along with a demo.

The version of HTMLArea used in Moodle 1.5.3, a course management system, was also modified to use these plugins. Download. Note that this required modification to several files that ship with Moodle, and this integration may not work in more recent versions of Moodle.

Survey Builder is a system designed for designing and implementing web-based surveys. It includes a design system, an administration system, and a presentation system.

Survey Builder is built as a set of PHP scripts. JavaScript is used in the Survey designer, and in the surveys for input validation. Results are stored in comma-separate-value (CSV) files. This system does not use MySQL or any other database system; it was designed for simplicity of setup.
