This is out of date information from Winter 2012.
Welcome to my Math 308 class. Here is the syllabus that will be distributed the first day of class. Once you finish reading it, you could get started on the first homework assignment.
If you need to contact me, now or any time this quarter, send an email to grigg@uw.edu. Please include the number 308 in the subject line of the email.
This feed will contain all announcements posted to this page.

The page www.kaleidoscope.net/greg/math/rref has a great row reduction calculator. You might find this helpful while you are learning to row reduce.
On the first day of class, we covered sections 1.1 and 1.2. Read sections 1.1-1.3 before class on Friday.
Don’t forget that the first homework is due Wednesday in class. Please write up your solutions neatly and staple your pages together.
If you must miss class on a day that homework is due, you can bring the assignment to my office hours on Tuesday or put it in my mailbox, which is located on the first floor of the C-wing of Padelford Hall.
As part of homework 2, which is due next Wednesday, you will have your first Catalyst problem. To submit the problem, you must follow the link on the homework page.
The problem must be submitted by class on Wednesday. Type your solution in the form that is given. The form will not accept any special formatting, so do the best you can to clearly communicate your ideas. Please do not submit your solution as an image or a link.
The written part of Homework 2 will be due on Friday this week Monday, January 23.
The Catalyst problem will be due on Wednesday as planned, even if the University of Washington cancels classes tomorrow.
For your first exam, you are allowed one page of notes, but no calculator. There are some exams from previous quarters posted on the exams page. The exam will cover all sections from Chapter 1 except for 1.4 and 1.8.
The first exam will be moved to Monday, January 30. See below for some information and resources.
We will cover 1.7 on Monday and Wednesday and 1.9 on Wednesday and Friday. A revised homework 3 will be due on Friday. The homework includes a Catalyst problem. You will not turn in homework from section 1.9, but there are some problems listed on the homework page that you should do before the exam.
CLUE will be holding a Math 308 midterm exam review on Thursday, January 26, from 8-10pm in MGH 234.
Answers to the first exam are posted here
We will cover section 3.1 and 3.2 today, and 3.3 on Friday and Monday. We are still a little behind from the snow days, but not enough to change any homework due dates.
Homework 4 will be due next Wednesday as originally planned. Unless I announce otherwise, the rest of the homeworks will also be due on Wednesdays. The second exam will definitely be given on Friday, February 24, as originally planned.
Your first exam has been graded. Grades are posted on Catalyst. This histogram will show you how you compare to the class. It is too soon to say how exam grades correspond to class grades, but I estimate a 28 on this exam corresponds to a 2.0.
Exams will be handed back on Friday. If you would like me to take a second look at how I graded a specific problem, please write a short explanation of what you think I overlooked and hand it to me with your exam.
Over the next few classes, we will be discussing some important examples of subspaces of Rn.
To help you out, I’ve prepared some notes: Null space, range, row space, and column space.
I will hold office hours from 3:00 to 4:00 on Tuesday, February 7, instead of at the usual time.
If you are struggling with the supplemental problem, this should get you started: If you are reflecting vectors across a plane and you want to find the plane, you want to look at all the vectors that do not move. In other words, you want to solve the equation Ax=x.
You still have a little more work to do, though, because this system of equations has variables on both sides of the equal sign.
Your second midterm exam will be given on Friday, February 24 in class. You may find some exams from previous quarters on the exams page.
The exam will cover sections 3.1 thru 3.8, except for a few topics from a few sections. A good guide should be that if I assigned homework on a topic, I might ask an exam question about that topic.
Note that we covered slightly less material this quarter than my class did in previous quarters, so there are a couple things on the practice midterm exams that I will not ask you to do on your midterm.
Specifically, I will not ask you questions about a linear transformation without giving a formula or description (Winter 2010 problem 3) or ask you to prove that a certain function is a linear transformation (Winter 2010 problem 6). I will probably ask about orthogonal bases, but definitely not about orthonormal bases (Spring 2010 problem 2b).
All of these are things that you could do, but that I did not assign homework problems on.
Answers to the second exam are posted here
Grades for Exam 2 are posted on Catalyst. If you want to see how you did in relation to the rest of the class, I have posted a histogram of scores.
Catalyst is also calculating a total class score for you. This percentage drops your lowest homework scores and assumes that your score on the final exam is the average of your two midterm scores. Each 2 points (out of 45) better your score is on the final than this average will add about 1.5 percentage points to your score.
I will need to rearrange my office hours for this week. I am cancelling both my Tuesday and Friday office hours.
I will instead hold special office hours on Thursday, March 1, from 12:00 to 1:30.
You are welcome to ask questions by email, or set up another time (probably next week) to meet with me.
We will finish up our study of eigenvectors by talking about eigenbases. This is closely related to diagonalization, which is discussed in section 4.7 of the textbook. You should read through the eigenbasis notes and do the exercises.
The final exam will be given at the university scheduled time, from 2:30 to 4:20 on March 14, 2012. The rules for the final exam are the same as for the midterms, that is, one page of notes and no calculators.
There will be a CLUE review session from 8-10 pm on Sunday, March 11 in MGH 254. You can also use the practice exams from the exams page to help you study for the final.
I will hold my normal office hours on Friday, March 9 and Tuesday, March 13. Please do not expect responses to emails sent on the day of the exam.
Grades for your final exams will be posted to Catalyst as soon as I have them. Course grades will be posted there as well.
If you would like to see your graded exam, you may come to my office hours any time during Spring quarter. My office hours will be posted here once Spring quarter begins.
