Math 2R03 - Theory of Linear Algebra
(Fall 2024)

MATH 2R03 is a second course in linear algebra. From the calendar:

In this course we will focus on the theoretical underpinnings of linear algebra, and in particular, we will emphasize the proofs of linear algebra. The main objectives of this course are: The prerequisite for this course is one of MATH 1AA3, 1LT3, 1NN3, 1XX3, 1ZB3, ARTSSCI 1D06 A/B, ISCI 1A24 A/B; and one of MATH 1B03, 1ZC3, 1ZZ5.

Homework

There will be nine homework assignments (your lowest two marks will be dropped). Assignments are posted below. Assignments will be submitted via Crowdmark. You will receive an email to your McMaster account that you will use to upload your assignment. All assignments due by 11:59PM on the due date.

Grading Scheme

I will calculate your mark using two different weightings. Your final mark will be the higher of the two weights.


Weighting 1
20% = 9 Assignments (best 7 used)
40% = Midterms (2 x 20%)
40% = Final Exam

Weighting 2
20% = 9 Assignments (best 7 used)
20% = Maximum of Midterm 1 and 2
60% = Final Exam

McMaster Polices

There are number of important McMaster Policies that you should be aware of. For a complete and up-to-date list of polices, see the official Course Outline.


With respect to MSAFs, missed work will be moved to final, as described in the course outline.
