Textbook: College Algebra and Trigonometry with Graphing Technology, David Stevens

Calculator: A graphing calculator is required for this class. I will be demonstrating with the

Texas Instruments-85. I will do my best to assist with other models, but I promise nothing.

Course Description: MAT 104 covers trigonometric functions of real numbers and angles, their graphs and properties, functions of multiple angles, identities, reduction formulas, radian measure, inverse functions, solutions of triangles, and complex numbers.

Prerequisite: A grade of C or better in Math 153 or equivalent and Math 103B or equivalent, or a satisfactory score on the Mathematics Assessment Exam.

Course Grade: Your final letter grade will be based on the usual grading scale:

A 90-100%, B 80-89%, C 70-79%, D 60-69%, F 0-59%

The following items will make up the course grade:

Homework: 150 points

Quizzes: 100 points

Exam1 (April 19):

Exam2 (May 16): 450 points

Exam3 (June 6):

Final Exam (June 19): 300 points

Homework: Homework will be due the class period after it is assigned. Homework not turned in at this time will be considered late. You may turn in homework up to one week after it is assigned for half credit. If all homework is turned in, and no more than three are late, the lowest regular exam score will be dropped.

Quizzes: There will be approximately 5 announced quizzes given over the quarter. These quizzes will be designed to help prepare you for the exams. Your lowest quiz score will be dropped. Since one score will be dropped, you may not make up a missed quiz.

Exams: Students are to bring a calculator, pencil, and blank scratch paper to each exam. If you cannot make it to an exam (final not included), you may take it up to 2 school days prior to the scheduled date. Otherwise, the exam may be made up after the scheduled date with a penalty of 10% per day.

Registration Information: You must register for this class at the Office of Admissions and Records. You may drop the class with no penalty or mark on your record on or before April 28. After April 28, you may drop the class and receive a grade of W until June 2. After June 2, if you are still enrolled, you will receive a grade of A, B, C, D, F or I.

How to Succeed in a Math Class: I am often asked how to successfully pass a math class, and here is my advice:

I) Come to every class session. Be prepared, and plan on participating.

II) Do your homework. Remember that what I assign is what I consider a bare minimum. If you need more practice, do it. Don’t make me be a homework enforcer.

III) Read the book. You paid good money for it, so you might as well use it.

IV) Make use of available tutors and my office hours. You will find tutors who know the subject matter in this course at the GMC.

V) Do math every day. Math is just like everything else: if you don’t practice, you become rusty.

Learning Disabled Students: It is important that students who are identified as being learning disabled speak to me about their special needs.

Course Schedule: The following is a tentative schedule. If things change (and I have money that says they will), I will let you know.
