Text: Graphs and Models, by Barnett, Ziegler, and Byleen.
Calculator: A graphing calculator is required and used for homework, quizzes,
and tests. Note: TI-89 and TI-92 are not allowed.
Bring your calculator to class every day.
Course Description: In this course, we will cover basic circular functions and
their inverses, trigonometric identities and equations, triangle trigonometry, law of
Sines and law of Cosines. Students may not receive credit for both Mathematics
108 and 106. This course along with Mathematics 104 will count for Mathematics
108.
Prerequisite: Mathematics 104 with a grade of C or better or placement.
General Goals and Objectives for the Course:
The goal of this course is to give students appreciation of mathematics and
trigonometry they need in order to be successful in other mathematics and science
courses. It focuses on problem solving, critical thinking and learning basic
concepts in trigonometry.
Course Coverage:
Chapter 5: Trigonometric Functions
5.1: Angles and Their Measure
5.2: Right Triangle Trigonometry
5.3: Trigonometric Functions: A Unit Circle Approach
5.4: Properties of Trigonometric Functions
5.5: More General Trigonometric Functions
5.6: Inverse Trigonometric Functions
Chapter 6: Trigonometric Identities and Conditional Equations
1
6.1: Basic Identities and Their Use
6.2: Sum, Difference, and Cofunction Identities
6.3: Double-Angle and Half-Angle Identities
6.4: Product-Sum and Sum-Product Identities
6.5: Trigonometric Equations
Chapter 7: Additional Topics in Trigonometry
7.1: Law of Sines
7.2: Law of Cosines
Exam: There will be 3 exams each worth 100 points. (Approximate dates: ends
of 5th, 10th, and 14th weeks.) Make-ups for missed exams will be available only
in very special circumstances. You must call before the scheduled exam in order
for a make-up to be considered.
Quizzes:
There will be many short quizzes (about 5 minutes long) at the
beginning of many class periods. These will be worth 5 points each. Quizzes must
be taken at the time they are scheduled in class, i.e., quizzes cannot be taken early
or made up at a later time.
Homework: Homework will be assigned for each section. These problems will
not be collected for grading but used for discussion.
Attendance: Attendance will count as 5% of your grade. Attendance will be
taken in each class. If absent, it is your responsibility to obtain the missed lecture
notes and to do the assignment. Those having 3 or more unexcused absences will
be penalized.
