*None* of these materials are derived from the Apex coursework. They're just assigned the unit/lesson numbers for convenience.

Many of these pages are not finished. This is mostly proof-of-concept experimentation. Use at your own risk.

5.1: Two-Variable Systems - Graphing

5.3: Two-Variable Systems - Elimination

6.3: Graphs of Exponential Functions

10.1: GCF and Factoring by Grouping

11.1: Solving Quadratic Equations: with and without leading coefficient

*weird why none yet?*

Content on these pages is all written and artisinally hand-coded by me (S. Rich), using the following tools:

- MathJax is used on some pages to display equations.
- KaTeK is used on some pages to display equations.
- algebra.js is used on some pages to manipulate equations and expressions.
- JSXGraph is used on some pages to display graphs and illustrations.
- Programmer's File Editor hasn't been updated since 1999, but it's still my favorite text-file editor.
- TI Calculator key fonts are being used to indicate which buttons should be pressed on the calculator.
- TI screen font is used on the fake calculator screens, to display simulated calculator output.
- The transfonter site was used to create webversions of Windows fonts.

For any of these to be useful, you need to have Tampermonkey installed as a Chrome extension (and, then, you need to be using Chrome).

See available Tampermonkey Scripts.
