  Text: Linear Algebra and its Applications, Second Edition by David Lay, published by Addison-Wesley.

  Tests: There will be three tests and a final exam. Each test will be announced in class one week in advance. The tests are tentatively scheduled for Monday, Sep. 10; Monday, Oct. 8; and Wednesday, Nov. 5. The University has scheduled the final exam for Wednesday, December 12 from 11am to 1pm. Each test will be worth 100 points and the final exam worth 200 points.
  

  Missed exam policy: Missed examinations must be approved by the instructor.

  • There will be no make-up tests. The score for the first approved missed test will be computed from the score obtained in the corresponding part of the final examination. If a student misses more than one test, or if the missed test was not approved by me, the score for that test will be zero.
  • If you miss the final exam and if a make-up exam was not arranged with me in advance, you will receive a score of zero for the final examination, unless the conditions for an incomplete apply (see below).

  Homework: Doing the homework well and on a regular basis is critical in this course. This point cannot be overemphasized. Homework will be assigned regularly. Selected homework will be graded and a final score equivalent to one test, 100 points, will be assigned.

  Attendance: Students are expected to attend every scheduled class, and to be familiar with the University Class Attendance policy as it appears in the General Catalog. It is the student's responsability to keep informed of any announcements, syllabus adjustments or policy changes made during scheduled classes.

  Grades: The total number of points available on tests and homework is 600. Grades will be no lower than those set forth in the following table:

  540 < points	90% to 100%	A
  480 < points < 539	80% to 90%	B
  420 < points < 479	70% to 80%	C
  360 < points < 419	60% to 70%	D
  points < 359	0% to 60%	E

  The grade of I will be awarded if all the following conditions are met:

  • The student has completed all but a small portion of the required work.
  • The student has scored at least 50% on the work completed.
  • The student has a valid reason for not completing the course on time.
  • The student agrees to make up the material in a short period of time.
  • The student asks for the incomplete before grades are due, 48 hours after the final exam.

  Course contents:

  • Systems of linear equations, row reduction and echelon forms, solution sets of linear systems
  • Matrix algebra
  • Determinants
  • Vector spaces
  • Eigenvalues and eigenvectors, diagonalization
