Course Outcomes:
Upon course completion, a student will be able to:

Solve right-triangle trigonometric problems, including word problems.
Solve simple trigonometric equations.
Graph y =Asin(x), y=Acos(x), and y=tan(x) without a calculator.
Evaluate the six trigonometric functions without a calculator for the angles of a right triangle; an angle in standard position defined by a point in the plane; quadrantal angles; and special angles: 30°, 45°, and 60°, as well as those angles whose reference angles are 30 , 45 , and 60 .
Evaluate the six trigonometric functions for any angle in degrees or radians with a calculator.
Define degrees and radians. Convert between degrees and radians. Locate angles (in radians) on a unit circle.
Sketch an angle in standard position. Find and use reference angles. Find and demonstrate understanding of coterminal angles.
Use basic identities to simplify expressions involving trigonometric functions.
