About the class

Course Catalogue Description.

01:640:250. INTRODUCTORY LINEAR ALGEBRA (3) Prerequisite: CALC2. Systems of linear equations, Gaussian elimination, matrices and determinants, vectors in two- and three-dimensional Euclidean space, vector spaces, introduction to eigenvalues and eigenvectors. Possible additional topics: systems of linear inequalities and systems of differential equations.

Exams: There will be two mid-term exams and a cumulative final. The final will count 200 points. Each midterm will count 100. They will be closed book exams and student-prepared formula sheets will not be permitted. Missing one exam will result as immediate failure for the class

Quizzes and Homework: Homework problems are assigned for each section. Students are expected to work on the problems for a particular lecture prior to the class devoted to that material. Homework will not be collected. However, each week there will be a short 10 minute quiz consisting of one or two problems similar to the homework problems. The quizzes will count 100 points toward the term grade.

Make-up exams/quizzes policy: There will be no make-up quizzes or exams, except in case of documented emergency.

Attendance: I will record attendance each class, but it will not count for the final grade.

In summary, here are the components of the term grade with their maximum possible points:

Component Points
Hour Exams 200
Final 200
Quizzes 100
Total 500

Topics of Individual Lectures
