1. Computing the Values of Trigonometric Functions of Acute Angles Section 3.3

2. Objectives Find the exact values of the trigonometric functions of π/4 (45°). Find the exact values of the trigonometric functions of π/6 (30°) and π/3 (60°). Use a calculator to approximate the values of the trigonometric functions of acute angles. Model and solve applied problems involving right triangles.

6. Using a Calculator Make sure that the calculator is set in the correct mode. –When working with triangles, the calculator should be set to degrees. –When working with circles, the calculator should be set to radians. Round the values to the indicated number of decimal places.
