To work Exercises 57–77, begin by reproducing the graph in Figure 29. Keep in mind that for each of the four points labeled in the figure, r = 1. For each quadrantal angle, identify the appropriate values of x, y, and r to find the indicated function value. If it is undefined, say so. See Example 4.
Sin(-900°)
(Reference Example 4)
Find the values of the six trigonometric functions for each angle.
(a) an angle of 90°
(b) an angle in standard position with terminal side through (-3, 0)
(Reference Figure 29)
