Author: A. Givental
Title: Linear Algebra and Differential Equations

This is the honours version of linear algebra. The pace is quite a bit faster than Math 221. The textbook is very dense and expects you to absorb material quickly, without a lot of worked-out examples. If you need more detailed references, you can try either of the following two free online texts.

Math 223 vs. Math 221
Math 223 is the honours version of Math 221. The basic syllabus is the same for both courses, but Math 223 is significantly faster, harder and more theoretical. Math 221 teaches you problem solving techniques, Math 223 puts more emphasis on theory. In Math 223 we cover additional subjects, and go into more depth than 221. Homework problems in Math 221 are mostly routine, whereas problems in Math 223 will require independent thought and hard work.

You can switch down from Math 223 to Math 221 even after the initial 2 weeks add/drop period, althouth this requires permission of the undergraduate chair. The earlier you switch down to Math 221 the better.

Marking
Your mark will be based on homework assignments, two midterm exams and one final exam, weighted as follows:
  • Homework:   20%
  • Midterm I:   15%
  • Midterm II:   15%
  • Final Exam:   50%
When calculating your homework score, your two lowest scores will be dropped. No late homework will be accepted.

Exams
The midterm exams are scheduled as follows:
  • Midterm I:   Wednesday, October 7.
  • Midterm II:   Friday, November 6.
There will be no notes, books, calculators or "cheat sheets" allowed on any of the midterms. This holds also for the final exam.

No makeup exams will be given. If you miss a midterm, your final exam will count for 65% of your grade.

Other Information
Although the material covered will be largely the same in both sections of Math 223, the two sections will run independently. There will be no common exams, although an effort will be made to have a significant number of identical problems on the final exam.

The performance of this section in Math 221 level problems on the final exam will be used to scale up the marks of the whole section, so that, on average, you will not be penalized for taking the more difficult Math 223, rather than 221. Still, if you are having trouble with Math 223, you should switch down to Math 221 in order to avoid getting lost, in which case the rescaling will not help you.

The math department offers free drop in tutorials.
Times when TAs who should be competent in 223 are present: Mondays, 11:00-13:00, Fridays 13:00-15:00, or MWF 9:00-10:00
