Course Description


A comprehensive treatment of linear algebra and matrix theory. The subject will be approached in a relatively concrete manner.



Roughly 40% homework, 30% midterm, and 30% final. Typically, the pass-fail line has been approximately 60%. Those with high scores on the homework and midterm will be excused from the final. In the past those with about 90% of the possible points on homework and midterm have been excused.

Homework Policy:

Students may work together on homework problems but must write up their own homework in their own words and hopefully understand the solution.   

Homework will be due on Monday at 10:00 a.m. in your section homework box outside room 253 Sloan. At most one late homework set will be accepted, and only at your TA's discretion, if arrangements have been made in advance with your TA, and if the work is less than a week late. Other than in exceptional circumstances, homework will not be accepted more than a week after the deadline.

Graded homework sets will be handed back in your section (and will be available during TA Office Hours). Solutions will be posted on the web.

Many of the problems which will be assigned this year in Math 1b, also were assigned in previous years in Math 1b. Do not consult the solution sets from previous years in working


Go to the recitations! Some weeks, a portion of the recitation may be dedicated to introducing some computational (or even theoretical) aspect which the Instructor will not have time to present in class. In general, get to know your TA and bug him/her to death (figuratively speaking) with your questions, and try to fill in all the holes in your understanding of the subject.
