The point (5, −2) is on the terminal ray of angle θ, which is in standard position. Without evaluating, explain how you would find the values of the six trigonometric functions.

How do you determine the exact values of the six trigonometric functions of the angle if the point (4,−4) is on the terminal side of an angle in standard position?

The point (8,-15) is on the terminal side of an angle in standard position, how do you determine the exact values of the six trigonometric functions of the angle?
