Class notes
Click here for the class notes, and here for the class notes in handwritten form. If you find some inconsistency or something that seems wrong in the class notes, it is likely a typo. In this case, double check the handwritten class notes and let the instructor know so that the notes can be corrected. Here are some complementary notes, whose section 1 complements section 1.2 of the textbook, and sections 2 and 3 complement sections 1.3 and 1.4 of the textbook.
