7.3 Computing the Values of Trigonometric Functions of ...

The exact values of the trigonometric functions for the angles {5 = 30°, 7T = 450, and 7T = 60° are relatively easy to calculate, because the triangles that 4 3 contain such angles have "nice" geometric features. For most other angles, we can only approximate the value of each trigonometric function. To do this, we will need a calculator. ................
