Linear Algebra and its Applications, 4th ed., by David C. Lay.
Expected Background: Officially, the prerequisite is Calculus II. In reality, we will rarely use calculus; almost everything in this class is accessible with only a pre-calculus background. On the other hand, this course will require somewhat more mathematical sophistication than the calculus courses you have probably taken, and will involve more proofs and disciplined conceptual thinking. Ideally, you have seen vectors before and have done some basic operations with them (adding, subtracting, multiplying by scalars). If not, please let me know. More generally, if you have any questions concerning your background, please speak to me as soon as possible.If you fall too far behind in this course, it will be very difficult to catch up. Please see me promptly if things stop making sense!
Mondays 12:45-1:45, Wednesdays 12:00-1:00. Kerchof Hall 208 (my office). If these times do not work for you, please make an appointment with me.
Homework will be due on Wednesdays. It is due in class If you are going to miss class for whatever reason, you must either submit the homework to my mailbox in the mailroom of Kerchof Hall before the beginning of class, or have a friend submit your homework in class. Late or improperly submitted homework will not be accepted. If you know in advance you will be unable to turn in homework when it is due, you should plan to turn it in ahead of time. If you have a conflict with a religious holiday, you must give me advance notice. I will drop your lowest homework score to allow for missed assignments or for assignments that pose special difficulty.
Homework must be neat, well-organized, and legible. In addition, it must be stapled or paper clipped
(no folding over the top-left corner or anything like that). Please
write in paragraphs, sentences, and English
words (oh my!) when they are called for. Many problems will
require you to write an explanation. The grader should not have
to decipher what you are doing--you should be clear and
unambiguous about your methods on a homework problem.
You are encouraged to work together on homework! But you must
write up your own solutions. I have found that it is helpful if I
think about the problems myself first, and then discuss the more
difficult questions with others.
Homework will be graded and every effort will be made to hand it back promptly. Grades will be posted on UVaCollab.
Schedule of Homework (the homework assignments themselves will be posted on UVaCollab)
Midterms will be in class on Wednesday, February 18th and Wednesday, April 1st.
If you have a conflict with one of these days, you must let me know now.
Another exam on the same day is not considered a conflict. If you have two other exams on the same day, talk to me.
The final exam is on Wednesday, April 30th, from 2:00PM-5:00PM.
Calculators are not permitted on exams.
20% Each Midterm
40% Final Exam
It is possible for exceptional class participation to be factored into the homework grade.
