Math 125 requires a textbook. The required textbook is Linear Algebra with Business Applications, by Sherbert and Brown, 3-d edition. This text includes a supplement in the back by Adawi and Royer.
We will cover chapters 1 through 5. A brief description of the material covered each week is given in the weekly schedule below. You are expected to read the textbook before the classroom discussion of each topic, as indicated on the schedule of homework and reading assignments.
A graphing calculator such as TI-83, TI-83+, TI-84 or TI-84+ is required. You may use it on exams, however, you will still be required to show work in most cases.
MATH 090 or a grade of C or better in MATH 121 or appropriate performance on the UIC mathematics placement test.
The course grade for the semester will be determined by Midterms, Quizzes, Homework and the Final Exam as shown below:
- 45% 3 midterm exams
- 30% Final exam
- 10% Homework
- 15% Quizzes
