I. Course Description
This course presents exponential and logarithmic functions, trigonometric
functions, complex numbers and polar coordinates. The course is designed to
prepare students for engineering calculus. Prerequisite: One semester of precalculus or its equivalent.
II. Instructional Materials
Textbook: Precalculus, Sullivan, 8th Edition
Pearson, Prentice Hall, 2008
Calculator: A graphing calculator is required for this course. I will be using the
TI-83. However, you will be expected to do extensive amounts of
work without a calculator.

IV. Evaluation
All late work will be reduced in grade. No index cards, flashcards, or cheat sheets
are allowed during test or quiz or exams, except those provided by the teacher.
You will have only one class period to complete tests. The amount of time will
be specified for quizzes. Your exams will be completed in the time specified by
the school. You are not allowed to come back to finish on another day or later
that day.
Your semester grade will be determined by averaging all grades received on
homework, quizzes, tests, projects, other assignments, and the comprehensive
final exam. Each student will be required to do work on ALEKs. The amount of
time will vary from week to week (Usually 1 – 3 hours per week). You will
receive a grade for having completed this work, which will be equal in value to
homework.
V. Grading
The following percentages will be used in determining your final grade:
90%-100%
A
80%-89.9% B
70%-79.9% C
60%-69.9% D
below 60% F

VII. Attendance
Attendance and punctuality are important. Students should attend every class
meeting and be prompt in arriving to class. Class begins on time. You should be
in your seats and ready to begin when the period starts. Anyone late to the class
will be considered tardy. Students are not excused from class until the period
ends. You are not allowed to return to your vehicles during class.
