Text

Elementary Linear Algebra, Howard Anton, Wiley, 9th edition.

Objectives

The successful student will learn the fundamentals of linear algebra, including facts about matrices, vector spaces, linear transformations, and eigenvalue problems. I plan to cover chapters 1 through 7 of the text.

Homework Policy

Homework exercises will be assigned for each class. While completed homework generally won't be collected, doing homework will help with the quizzes and exams. I encourage group participation in the solution of exercises.

Quizzes

There will be about 6 announced quizzes during the semester, administered at the beginning of the specified lecture. Quizzes will be comprised of two to four short questions based on the homework exercises that you have attempted. See the schedule below.

Examinations

There will be two midterm exams and a comprehensive final exam. See the schedule below for planned examination dates.

Grades

Grades for all assignments will be available on Online@UT. The final grade (as a percentage of the total points) will be computed using the following weights: quizzes 30%, midterm exams 40% (20% each), and final exam 30%. Letter grades will be assigned according to the following scale:

100 >= A >= 93 > A- >= 90;

90 > B+ >= 87 > B >= 83 > B- >= 80;

80 > C+ >= 77 > C >= 73 > C- >= 70;

70 > D+ >= 67 > D >= 63 > D- >= 60;

60 > F.

I reserve the right to change this scale, provided the change benefits all students.

Academic Honesty

Student's must be familiar with the ACADEMIC STANDARDS OF CONDUCT section of the Hilltopics student handbook.

Accommodation of Disabilities

Students who require a course accommodation due to a documented disability should contact the instructor and the Office of Disability Services (ODS). ODS is located in 2227 Dunford Hall and may be reached by telephone at (865) 974-6087.

Class Schedule and Assignments

During the semester I'll post the schedule, along with assignments, exam solutions, and class notes below. There may be deviations from the schedule below, which I will announce in class. Ultimately, you are responsible for knowing what is covered and assigned by regularly attending classes. Please bookmark this site.
