3. A point on the terminal side of an angle is given. Find the exact value of each of the 6 trig functions. 1.) (-3, 4)2.) (-3, -3)3.)

4. Reference Angle: Given an angle. is the acute reference angle formed by the terminal side of and the horizontal axis. One of the sides of the reference angle is always the horizontal axis. The + or – sign depends on the quadrant. This is also true for the remaining 5 trig functions. Reference angles are always positive acute angles.
