Placement: There are two other linear algebra courses at Brandeis, Math 15 and Math 22a, and choosing correctly is important. Roughly speaking, the topics in covered in Math 22 are similar to those in this course, but the treatment is more theoretical and somewhat faster paced. The two courses have the same schedule, to simplify changing between them. Math 15 is a much less theoretical course than either 21 or 22 (you won't do very many proofs) and also covers much less ground. You are strongly advised to discuss your placement with me and/or Professor Lian (Math 22), or one of the department's undergraduate advisors, Professors Igusa and Monsky.

There will be a short diagnostic (ie grades don't count) quiz on the first day of class, to help you decide which course is for you. The same quiz will be given on the first day of Math 22.

Math 21a on the web: I will try to have everything concerned with the class posted on the class homepage, On this page you will find up-to-date course information (eg changes in office hours or exam schedules), the homework assignments, and supplemental course materials. We will have a class mailing list; I will explain how to access this on the first day of class. If you are feeling adventurous, you can try to figure things out on your own by looking at the Brandeis lists page . Click on the link "Lists for classes offered at Brandeis" and then find math-21a on the list of offferings.
