History
As a project for math class, I decided to use my programming skills to build a site that people could use. As the class went on, I added various tools to the site, including a Euler's method calculator, a Density Map grapher, and a Differential Field Grapher. The site uses python code built around Google Appengine to calculate values, and uses jsDraw for graphs. My math teacher actually ended up listing my site on his teacher website as a helpful link.
