TEXT: ALGEBRA & TRIGONOMETRY-GRAPHS & MODELS by Bittinger/Beecher/Ellenbogen/Penna, Addison Wesley Publishing Company, 1997.

PREREQUISITE: Placement or MAT 113.

COURSE DESCRIPTION: Trigonometric functions, right triangle trigonometry, solving oblique triangles, graphing trigonometric functions, inverse trigonometric functions, trigonometric identities, applications of trigonometry, complex numbers, exponential, and logarithmic functions.

OBJECTIVES OF THE COURSE: In general, the course is designed to develop an understanding of trigonometric language, reasoning, applications, and skills necessary for success in calculus.

TEACHING METHODS: Learning mathematics is "doing" mathematics. Therefore, classes will consist of modeling of examples by both instructor and students. Opportunities for group and individual intuitive understanding of trigonometric concepts, skill development, and problem-solving will be provided. within a technological context. Students are required to attain a graphing calculator (TI-82/83 is recommended). Instructor/student and student/student interaction is encouraged.

ATTENDANCE: Punctual attendance is required. The College attendance policy as stated on page 61 of the catalog will be strictly enforced. No more than three absences are allowed. Three tardies count as an absence. Two quiz/homework grades will be dropped for all students that stay within the three absences limit. There will be no make-up tests or exam for unexcused absences. Make-up daily assignments should be turned in by the next class period after the absence occurred. The instructor should be notified in advance of excused absences due to college approved events.
 
GRADING:
Homework and Quizzes
15% 
Chapter Tests
60% 
Attendance
5% 
Final Exam
20% 

I will assign homework each class period. Quizzes may be announced or unannounced.  The final exam will be comprehensive. A 10 point grading scale will be used. You will frequently be asked to explain your thinking on various exercises/problems orally and in written format. Strive for understanding of all concepts.

FINAL EXAM — Monday, May 8, 1:30-3:30pm

CHEATING AND PLAGIARISM: A scholar is characterized by his/her honesty and fairness. Therefore, a scholar neither gives nor receives "information illicitly with intent to deceive the instructor in his or her effort to grade fairly any academic work" (NCWC Catalog, p. 64). Also, a scholar does not take credit for someone's work without giving credit to the creator. The violation of these principles is academic dishonesty and will not be tolerated. The instructor will adhere strictly to the plagiarism and cheating policy as stated in the catalog on pages 64-65.


MATH 115: TRIGONOMETRY

A Graphing Calculator (TI-82 or TI-83 preferably) is required and can be rented from Dr. Lawrence for $82.50 (to be refunded when the calculator is returned) on a first-come, first-serve basis.
