Find each exact function value. See Example 3.

sin (-8π/ 3)

Find each exact function value. See Example 3.

sin (-7π/ 6)

Find each exact function value. See Example 3.

tan (-14π/ 3)

Work each problem.

Consider each angle in standard position having the given radian measure. In what quadrant does the terminal side lie?
