RADFORD UNIVERSITY RADFORD, VIRGINIA COURSE PLAN Course Number and Title: Math 140 – College Trigonometry Prepared by: Richard Fisher Date: Fall 2012 Approved by ________________________ Date: ________ 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. III. Course Content The following objectives will be addressed in this course: Composition of functions Inverse functions Translations of exponential functions Evaluating exponential functions Solving exponential equations Translations of logarithmic functions Evaluating logarithmic functions Solving logarithmic functions Applying the rules of logarithms Inverse properties of logarithms and exponentials Applications of logarithms and exponentials Convert radians to degrees and degrees to radians. Find radius, angles, and arc lengths of sectors Find areas of sectors Determine values of the six trigonometric functions Graphing the sine and cosine functions Determine amplitude, period, and phase shift of a trigonometric function Graphing the inverse trigonometric functions Evaluating the inverse trigonometric functions Applications of trigonometric functions Trigonometry of right triangles: determine the values of unknown sides and angles Applications of right triangle trigonometry Trigonometric identities The trigonometric addition and subtraction formulas The double and half angle formulas Solving trigonometric equations The Law of Cosines The Law of Sines The trigonometric form of complex numbers De Moivre’s theorem Finding the nth roots of unity Polar coordinates Graphing polar equations The Ellipse The Hyperbola The Parabola Sequences Sums of Finite Sequences Arithmetic Sequences Geometric Sequences Infinite Geometric Series 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 VI.

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.
