math notes

Sheila Liming: Writing is the act of trying to create a record of your understanding of something. (from the Ezra Klein Show Podcast, Episode ‘The Quiet Catastrophe’)

Collection of math/cs notes and problems written up over the years for my own amusement. Topics are at the undergraduate college level. Normally notes like these would be written with a pencil in a notebook. LaTeX makes it very easy to produce publishing quality typesetting of mathematical texts, so blame LaTeX for this collection. Hopefully others will find some of these useful. Also available is the whole collection as one book and the Github repo with all the LaTeX sources.

Errors and misunderstandings in these notes are solely my fault. Nothing here is original. I tried to be complete about attributions and citations but if I missed something, I apologize.

Also caveat emptor: Nobody has done any proofreading on these notes.
