Disclaimer These notes are written in their entirety by me, David Duan, while attending lectures at the University of Waterloo. I have no intentions of violating any UW policies and will gladly honour takedown notices produced by an authorized UW representative (contact me here). They are by no means authoritative so use at your own peril. Otherwise, have fun losing hair :)

Remark. Check out my friends' sites with more notes:

Remark. Courses in gray means either I'm taking the course right now or I haven't had the chance to fully clean up the notes.
