Final Exam info and review material
The final exam in next Thursday, 12/16, from 8:30-10:20am, in our classroom. You're allowed one hand-written two-sided notesheet, but no calculator.
There are two practice exams, with solutions, on the practice exams page. One of them is the exam you worked on in class Friday.
The answers to most of the Supplementary and Conceptual exercises, at the end of Chapters 1, 3, and 4, are also there.
Your grades should be up to date, except for the last homework. Let me know if you have any questions.
Week #9 and #10 info
There is no class on Wednesday Nov. 24 or Friday Nov. 26. I encourage you to get a start on the next homework, especially if you've seen determinants before. Extra credit #5 is due in class Monday Nov. 29th. Midterm II solutions are also posted.
Section 4.3 is somewhat optional - it's about simplifying determinant calculations using row and column operations. If you're curious, it wouldn't hurt to give it a read - it'll deepen your understanding of how determinants work. However, I don't think this is an important skill, now that we're in the computer age - about as necessary as knowing how to use a slide rule. I'll mention some of the results in class, but won't dwell on it.
Optional extra credit 5 - pure or applied
due by November 29th in class

Week #8 - Midterm II info
We will have the second midterm in class on Friday, Nov. 19. You're allowed a two-sided note sheet, but no calculator. The midterm will cover all of Chapter 3 except for the material in Sections 3.7 and 3.9. There won't be questions solely on earlier material, but you of course will need to know those tools, e.g. how to row reduce a matrix. There are practice exams on the 'practice exams' page. Homework #8 is posted, but will not be collected. If anyone is interested, I've also made up another extra credit problem, due the Monday after Thanksgiving - see below.
Grades up to 11/6
You can see all your grades, and the number of weekly surveys you've completed, by going to the
Gradebook
and entering your UWNetID
. The first two extra credit assignments were worth 3 points each, and will be added to your homework score. The third extra credit assignment, on nilpotent matrices, was worth 5 points, added to your Midterm I score. Remember, the lowest HW grade is dropped, and you want to try not to miss more than two weekly surveys (see syllabus).
As for how I'm grading/curving the class, I'm going to wait until the end of the course to see the distribution of scores, before extra credit. I'll set the median at a 3.2, with a linear distribution on either side
.
Short proofs from Oct. 20th class
I wrote up clear proofs of the three statements we worked on in class on Wednesday, with some comments.

If anyone is interested, I've also made up another extra credit problem. See below.
