Textbook: Linear Algebra, Fourth Edition, by Friedberg et al., published by Prentice Hall.
IMPORTANT: See the note about the textbook on the syllabus. In particular, the textbook is not required.

Course Syllabus: ( pdf version)
The syllabus will include information about grading policies, exam schedules and policies, etc. You should definitely read it.

How this course will work.
This handout ( pdf version) has more on the big picture and the details of how this course will work, which is probably different than what you might be expecting. It is an absolute must read.

"I hear, I forget. I see, I remember. I do, I understand." - Chinese proverb.

Homework:
As mentioned in the syllabus, there are three kinds of homework in this class: The rough drafts, the class presentations, and the final drafts. Each will come from the "master homework list" which is linked below.

The master list of problems ( pdf version), from which the 3 kinds of homework will be assigned.
- Problems 70-170
The rough draft problems. These will be due every Firday.
The final draft problems. These will be due every Monday.
The in-class presentation problems, which will be done every day in class. This list will be updated very frequently, so you sould check it very frequently.

Definitions and Theorems:
Periodically in class we will need some definitions, and we will come across some theorems that I consider to be the "big" theorems. The definitions will be posted below as needed, and each "big" theorem will also be posted below, after someone in the class has presented a proof of it.

Definitions.
The "big" theorems.

Announcements:

We now have a TA, Aisha Najera. Her office is Math 614, and she will have office hours Thursday 11-12 and Friday 10-11. Her email address is anajera@math.arizona.edu.
Our first exam is Friday, September 29th in class. Expect to see a couple "Give the definition of..." questions, a couple questions asking you to reprove things we've already proven (i.e. problems from the list), and a couple of problems that make you think on your feet (using the stuff we've done). I'll try my best to keep it short enough to reasonably fit in 50 minutes.
We're moving the exam to Monday, November 20th.
Here are solutions to exam 1 and exam 2 .
