Course Description: The purpose of this course is to learn about matrix theory and its applications. More generally, we will learn basic principles of linear algebra.
The course will follow the text rather closely. But it is strongly advised to attend class, as the instructor will offer many ideas and insights not to be found in the book. It is also important to keep up with the homework.
Work Required in the Course: There will be weekly homework assignments.
The relative weights of the course components are as follows:
Homework: 20%
Midterm I: 20%
Midterm II: 20%
Final Exam: 40%
TOTAL: 100%
If you are taking the course Pass/Fail, then the cutoff for a pass is C -
or 65 percent.
There are help sessions for Math 309 beginning 1/25/2023 in Room 132 of the Learning Center
