News and Information

12/4/09: See here for an explanation of how your final course letter-grade will be assigned.

12/2/09:  Welcome back! There will not be a quiz this Thursday. Your next chance to show what you know will be in the Final exam. See here for details.

11/08/09: The second midterm exam will be in class on Tuesday November 17. See here for details.

10/19/09: There will NOT be a quiz this Thursday. The next quiz will be on Thursday October 29.

10/6/09: The quiz on Thursday will NOT cover the parts of Section 3.2 that we haven't yet done in class, i.e. it will cover the parts of Section 3.2 up to the end of page 195.

9/29/09: There will NOT be a quiz this Thursday. The next quiz will be on Thursday October 8.

9/19/09: I have slightly modified the syllabus for the midterm. We didn't get quite as far as planned in last Thursday's lecture, so I have removed Section 2.3 and the last part of Section 2.2. To help you study, I prepared a summary of the main ideas and results we have covered so far. You can find it here. Other tips for the midterm:

  • Some of the questions will be taken from the homework problems
  • You should definitely know - and understand - the definition of linear independence.

    9/15/09:

  • The first midterm exam will be on in class on Thursday September 24. See here for details.
  • See here for Quiz solutions.
  • Note that the syllabus for Thursday's quiz includes only the part of section 2.2 that we covered in class last Tuesday, namely the part up to Theorem 5

    • 9/14/09:  I've just realized that I inadvertantly skipped over section 1.7. We should have covered it before starting chapter 2. I've updated the Lecture Log and the syllabus for Quiz 3 to take this into account. We'll cover section 1.7 in class tomorrow. Sorry about that!

    8/31/05:   The first quiz will be on Thursday September 3. It will cover Sections 1.1. and 1.2

    8/25/05:   Welcome to the class!

    Linear Algebra and its Applications  (3rd Edition) by David C. Lay (Addison-Wesley, 2002)

    Syllabus

    Chapter 1, Sections 1-7
    Chapter 2, Sections 1,2,3,6
    Chapter 3, Sections 1-3
    Chapter 4, Sections 1,2,3,5,6
    Chapter 5, Sections 1-3
    Chapter 6, Sections 1-3, 5-6

    Grading

    Your grade for the course will be determined by a weighted average of your scores for weekly quizzes, 2 midterms and a final.   The weights of each will be:

    Quizzes 15%
    Midterms 1 25%
    Midterms 2 25%
    Final 35%
    Letter grades for the course will be `curved', with the class average corresponding to the boundary between a C and a B. The class averages to-date, i.e. for the 8 quizzes and 3 midterms, are
    Quizzes 88/120=73%
    Midterms 1 60/75= 80%
    Midterms 2 49/70=70%
    The weighted average to-date is thus (0.15*73 + 0.25*80 +0.25*70)/0.65= 75%.
    If the class average for the Final is F%, then the weighted average for the course will be (0.65*75+0.35*F)

    Resources

    Study guides, review materials, data sets, case studies and applications, and additional resources can be found at this web site for the course textbook: www.laylinalgebra.com/free_site/index.html

    Homework

    Homework will be  posted at this website.  The homework will not be graded but this doesn't mean it's unimportant! The best (maybe the only) way to learn the course material is to work examples. As added incentive to do the homework, all exams (midterms and final) will include questions either taken directly from, or modeled closely on, the homework sets.

    Homework 1 Homework 2 Homework 3 Homework 4 Homework 5 Homework 6 Homework 7 Homework 8

    Exams

    There will be weekly quizzes, two midterms and a final exam. Dates and syllabi will be announced at least one week in advance. The (tentative) dates for the midterms are Thursday September 24 and November 12.
