Text: Most of what we’ll cover is found in Linear Algebra and its Applications, 4rd Edition, DavidC. Lay. Problem assignments are taken from there.

Grading: Homework: 10%Quest Assignments 20%2 Midterm exams: 40%Final Exam: 30%Total: 100%

We will be using the +/- grading system: 90% is at least an A, 86.7% is at least an A-, 83.3% is atleast a B+, 80% is at least a B, etc.

Exams: Nearly chiseled in stone, the dates for the midterm exams are Friday Feb. 26 and FridayApr. 8. There are no make-up exams. If you miss a midterm, it’s not automatically a zero (butit might be a zero.) At the end of the course, I’ll make a rough guess as to what your score wouldhave been, and you’ll have to live with it. Midterms are given in lecture and will be closed-book,closed-notes, and no-calculator. The final exam is schedule for Thursday, May 12 from 2 to 5 p.m.Calculators will not be allowed on any exams.

Homework and Quest There are assignments from the text on the next page. You should workall the problems. A couple problems on each line are in boldface. You should prepare beautifulsolutions to those problems to hand in. Neatness and following directions count. Due dates willbe announced in class and only there. This course also uses the Quest system. Here’s the cannedparagraph: “This course makes use of the web-based Quest content delivery and homework serversystem maintained by the College of Natural Sciences. This homework service will require a $30charge per student for its use, which goes towards the maintenance and operation of the resource.After the 12th day of class, when you log into Quest you will be asked to pay by credit card on a securepayment site. You have the option to wait up to 30 days to pay while still continuing to use Questfor your assignments. If you are taking more than one course using Quest, you will not have to paymore than $60 per semester. Quest provides mandatory instructional material for this course. Forpayment questions, email: questfees@cns.utexas.edu.”. Normally each Quest assignment will bedue Friday at 5:00.

Canvas We use Canvas a little bit. The syllabus and other documents are posted there. We use itfor mass communication. We’ll report raw scores to you on Quest (rather than Canvas), so you cancheck our accuracy, but neither Canvas nor Quest determines your final grade.

Overview: Almost nothing in the universe is linear, but almost everything in the universe is almostlinear, and we often pretend that a curvy thing is really a straight thing. Matrices were inventedto deal with the linear relationships between linear things. In this course we learn the properties ofmatrices and use them to study linear objects, like vector spaces and the transformations thereof.

Students with disabilities: The University of Texas at Austin provides, upon request, appropriateacademic accommodations for qualified students with disabilities. For more information, contact theOffice of the Dean of Students at 471-6259, 471-4641 TTY

Health: It’s part of the students’ responsibility to keep themselves able. Please eat decently, sleepsufficiently and live in a clean area. A broken arm due to a mechanical bull ride is not an excuse formissing an exam. Stress and disorientation are common among university students, and a stressedout person gets sick more easily. You probably should treat your body and mind at least as well asyou treat your car, so don’t wait till you crash and burn before availing yourself of the many, freeservices UT offers. For instance:

Pet PeevesA. I don’t take“walk-ins” outside of regular office hours. If it’s regular office hours,please just drop by. Otherwise you need to make an appointment. Just send me ane-mail with the times that would work for you. (Really, have you ever heard of a“math emergency?”)

B. Some students want to sit in a corner of my office and work on their homework,only bothering me when or if they get stuck. I don’t like this. Dude, you’re in myspace. (Also: Reasons.)

C. Please don’t walk with me after class. Usually, I need to decompress a bit beforethe next class, so please let me have a few minutes alone with my own thoughts.

D. Please don’t give me anything. No cookies, no homebrew, no bookmarks, etc.

E. When class starts, stop talking instantly. Don’t finish your very, very importantsentence. Just stop.

F. If you’re going to be more than 2 minutes late to class, please don’t bother coming.That way you won’t be disrupting the students.

G. If I ask you to leave the classroom, that is not an opening for a debate aboutwhether you really have to leave. By the time I have to ask, it’s already far too late.Just quietly leave and come back the next class with a new mode of public behavior.

H. I really1,000,000 hate to be asked for make-up anything. “But it’s a universitysanctioned event!” So what? “But I have 75 doctor’s notes!” Sucks to be you. “Well,it can’t hurt to ask!” Yes. Yes it can.

I. Freakin’ cellphones. What the hell is wrong with you people? Are you trying tobecome the Borg, fercrynoutloud?
