### Announcements

• The final exam has been graded. Most people did very well, in fact the average score was 76 out of 80. As a result, for most people the final grade is higher than the midterm grade. Both the final results and the grades are posted on WebCT. I will be in the office most of the afternoon tomorrow (Thursday). You are welcome to come by to take a look at your exam. I cannot give it back to you, but I also have a stack of homeworks and quizzes that I would like to return.
• If you liked the material in this class, consider grading for it. You can get all the information at this site. Have a great break!

Office hours: M 2:50-3:50, W 11:30-12:30, Th 1:30-2:30, or by appointment.
Text: Steven J. Leon, Linear Algebra with Applications, 7th edition, Pearson Prentice Hall, 2006.

Prerequisites: Math 152, primarily familiarity with analytic geometry and vectors. Knowledge of differential equations may be helpful on occasion.
Course outline:
• Solving systems of linear equations. Matrices. (Chapter 1)
• Determinants (Chapter 2)
• Vector spaces, linear independence, bases (Chapter 3)
• Linear transformations (Chapter 4)
• Orthogonality, inner products, orthogonal bases (Chapter 5)
• Eigenvalues and eigenvectors, diagonalization (Chapter 6)
Exams: We will have two in-class tests on September 20 and October 27. The final exams for the two sections of the class are on Monday, December 11, 10:30-12:30 (the 12:40 section) and on Tuesday, December 12, 3:30-5:30 p.m. (the 1:50 section). If, under completely exceptional circumstances, you need to miss one of the tests, a make-up exam will be given. Only University-approved excuses will be accepted, and you have to let me know preferably in advance, and no later than 2 days after the exam. The exams are closed book, closed notes, and calculators are not permitted. You should bring your ID to all tests.

Scholastic Dishonesty: Cheating of any form is not acceptable and it will be dealt with harshly. In particular, copying work done by others, either in-class or out of class, is an act of scholastic dishonesty and it will be prosecuted to the full extent allowed by university policy. Collaboration on assignments is permitted for this course, however each student must write up her or his own solutions. For more information on university policies regarding scholastic dishonesty, see the University Student Rules.
Aggie Honor Code: "An Aggie does not lie, cheat, or steal or tolerate those who do."

Homework: weekly, due on Fridays in class. Homework problems may appear on the exams and quizzes. You are encouraged to work together, but straight copying of homework is not allowed. Late homework will not be accepted, but the lowest homework score will be dropped.
Quizzes: There will be short quizzes in class, approximately one for every two homework assignments, announced in advance. The lowest score will be dropped.
Grading: Homework and quizzes 30%, each midterm test 20%, final 30%.

Other important dates: September 1 (last day to add or drop a course), November 3 (last day for a Q-drop ).
Students with disabilities: Come talk to me no later than the first week of classes. "The Americans with Disabilities Act (ADA) is a federal anti-discrimination statute that provides comprehensive civil rights protection for persons with disabilities. Among other things, this legislation requires that all students with disabilities be guaranteed a learning environment that provides for reasonable accommodation of their disabilities. If you believe that you have a disability requiring an accommodation, please contact the Department of Student Life, Services for Students with Disabilities, in Room 126 of the Koldus Building or call 845-1637."
Attendance: According to the University Student Rules, absence for three or more class days requires a University-approved excuse and documentation.

Keys to success: Attend class (of course :) Solve all the homework problems, well before the exams. Spend more than seven hours per week working on the problems. Form study groups to discuss the course material and homework problems. Read ahead in the text.
