In the unit circle shown in the figure, points A, B, C, D, and E correspond to the angles o, and respectively. The coordinates of the
points are shown in the figure.
You have learned that for any point (x, y) on the unit circle that corresponds to an angle 8, sin 8 = y and cos 0 = x. Using the unit circle, find the
values of all six trigonometric functions for the five angles and complete the table.
