## Math Analysis Notes, Problem Sets, Playlists

These are notes, problem sets, and playlists for Math Analysis. Half of the playlists are me doing the notes. The rest of the playlists are supplementary problems and explanations. Click the top headings for the actual notes--they don't look like hyperlinks, but they are! Math Analysis is a great pre-calculus course: you learn everything you need for Calc 1, Calc 2, and Calc 3 (as well as AP Calculus AB and BC).

If you have noticed any errors in the notes, I'd really appreciate it if you'd point them out to me. You can do that using this form.

## Notes 1

Radians, arc length, basic stuff about trigonometry in the plane, coterminal angles, degrees, minutes, seconds. Here's a GeoGebra file that shows radians on a circle. I recommend downloading it and playing around to get a better sense of how radians work.

## Inexcusable Problem Set

This is a collection of some big ideas type questions that you should definitely be able to solve by the end of Notes 12, which we've now reached. Note that it's inexcusable not to be able to solve them...that doesn't mean you will be able to--just that there's no excuse for not being able to, really.

## Notes 13

Random stuff about functions, rational functions, that kind of stuff...some basic limits at infinity. Here's a little write up about how to graph two different rational functions.
