Mathematics Coursework and Lecture Notes
During math classes, I like to LaTeX notes to these classes in real time. On this page, I've included copies of notes to current and past courses.
Currently, I liveTeX notes using latexmk and a heavily modified Vim editor. (For details on the technical setup, see the corresponding FAQ.) Since these notes are written during class, it is quite likely that they contain typos. Please send any corrections to me via email.
For more polished exposition on some selected topics, see the Napkin project.
Here is a download link for descriptions of all courses, even including the ones which I do not have notes for. (The list below just includes the one for which I have notes to share.)
