Free lecture notes

My day job is in math education at a college level. In the hope of providing access to all students, I am providing my own original lecture notes for free use.

All students and educators are welcome to read and learn from these notes. However they are my intellectual property, so they may not be presented as anyone else's original work in any context. If you intend to teach out of my notes, please contact me for permission. They are not to be reproduced in part or in whole without my consent.
