Graphing Tools

Java Graphers: 2D, 3D, and Differential Equations (Web based - Any platform)
SVG 2D grapher: A 2D graphing tool using SVG (Web based - Any platform)
DP-Graph Frontend.: A web-based frontend to our 3D graphing software - Requires download of DP-Graph (PC only, Pierce students/staff only)
DP-Graph Frontend for older browsers (no frames or javascript): Requires download of DP-Graph (PC only, Pierce students/staff only)
DP Graph info: Brief instructions for direct use of DP-Graph
A handy free graphing calculator program (PC only)

Statistics

Histogram Grapher (web based): Draws a histogram from a frequency table. Does not do any calculations
BoxPlot Grapher (web based): Draws comparative boxplots from one, two, or three 5-number summaries. Does not do any calculations
Hypothesis Test Graph Generator (web based): Creates an graph of the normal curve or t-distribution, and can shade critical regions and show the location of the test statistic. Does not do any calculations
Normal/t Probabilities (web based): Calculates probabilities for a normal or t distribution, given mean and standard deviation
Stats Tables (external link): Calculate p-values or find critical values for normal, t, chi-square, F, and other distributions
Better Histogram Excel Add-on. (Requires Excel): This add-on for Excel (shows up in the Tools menu) will allow you to create a histogram with horizontal axis labels at the lower class (bin) limits. This version is one that I have modified. The original is available from treeplan.com

Computer Algebra

Sage (web based, requires free account): A free web front-end to a package of computer algebra software, including Maxima and others.
Maxima Symbolic mathematics software.: This program (PC only, Unix version available) has symbolic calculation funcationality as the TI-89/92 and computer algebra software like Maple or Mathematica. The user interface leaves a bit to be desired.
Euler Numerical Mathematics Software.: This program (PC only) is designed for numerical calculations and algorithm design. It is similar to MatLab.

Programming/Web

Text to XHTML+MathML converter: Converts text and math expressions into web-ready format (Web based - Any platform)
Using AsciiMathML: Instructions on using AsciiMathML to put math on your webpages using MathML and a text-based entry method that requires no knowledge of MathML (Web based - Any platform)
A simple PHP script to list all PowerPoint files in a directory: Right-click and "Save As.." listpp.php
