Chapter 6 Trigonometric Functions (TR)
Objectives
How can we use right triangles to make sense of angles?
By the end of this chapter, you should be able to...
-
Convert between degrees and radians. Draw angles in standard position.
-
Identify and find coterminal angles. Find the length of a circular arc.
-
Use a right triangle to evaluate trigonometric functions.
-
Find exact values of trigonometric functions of special angles (30, 45, and 60).
-
Use reference angles, signs and definitions to determine exact values of trigonometric functions.
Readiness Assurance.
Before beginning this chapter, you should be able to...
-
Identify the quadrant of a point on the coordinate plane.
-
Determine the measure of a missing angle of a triangle when given two angles.
-
Use the Pythagorean Theorem to find side lengths of right triangles.
-
Determine the relationships between the angles and sides of a triangle.
-
Find the circumference of a circle.
