- Learn to solve linear systems
- Learn how to apply linear systems to problems from various disciplines
- Learn the basic properties of vector spaces

Linear algebra is an essential part of the mathematics, science and engineering disciplines. The material in this course will be very important in your future studies.

**Homework**

The homework assignments will be given on class and listed on the course web page. Completing these exercises is essential to your mastery of the material. Homework will be collected each week in conference and selected problems will be graded. Late homework will not be accepted without prior arrangement with the instructor. Homework scores will count as 15% of your final grade.**Exam**

There will be two hour exams during the term. Each will count 25% of your final grade. Tentative dates are September 12 and October 3. There will also be a comprehensive final exam in the last week of the course, probably on Thursday. This exam will count as 35% of your final grade.
