Unit 1
Trigonometric Functions

Unit Objective
Understand the signs of the trigonometric functions of any angle; use radian formulas for area, arc length, and velocity. This unit should take no more than 1 1/2 weeks to complete.

*All assignments are in Basic Technical Mathematics With Calculus 7th edition by Allyn J. Washington, 2000.

Method of Evaluation
The unit test will be a pencil and paper exam given at your class site. The test will be administered by the instructor or by a proctor. Please see the course schedule for the exact time and date of the unit test.
