Concept Check Sketch an angle u in standard position such that u has the least positive measure, and the given point is on the terminal side of u. Then find the values of the six trigonometric functions for each angle. Rationalize denominators when applicable. See Examples 1, 2, and 4.
(-8, 15)
(Reference Example 1)
The terminal side of an angle u in standard position passes through the point (8, 15). Find the values of the six trigonometric functions of angle u.
(Reference Example 2)
The terminal side of an angle u in standard position passes through the point (-3, -4). Find the values of the six trigonometric functions of angle u.
(Reference Example 3)
Find the six trigonometric function values of the angle u in standard position, if the terminal side of u is defined by x + 2y = 0, x 0.
