Math Applications & Function Generators

Most of the stuff on this page runs in JavaScript. These are just some applications I have either written or found useful at some point (if they aren't mine, the credits are in the script...do a "view source"). You can find more JavaScript math generators at JavaScript.internet.com. What mathematical functions are supported by JavaScript? Answer below.
