### COURSE MATERIALS

Math 125 requires a custom textbook with a MyMathLab Access Code. The required textbook is *Math 125* custom edition for UIC, available in our bookstore only.

We will cover chapters 1 through 6. 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.

### PREREQUISITES

MATH 090 or a grade of C or better in MATH 121 or appropriate performance on the UIC mathematics placement test.

### GRADING

The course grade for the semester will be determined by Midterms, Quizzes, Homework and the Final Exam as shown below:

- 100 points each on 2 midterm exams
- 200 points for the Final exam
- 80 points for online Homework
