Move the highlighted point to find the coordinates of points on the unit circle. You can then use these coordinates to write the values of trigonometric functions for a given angle.
Can you evaluate all six trigonometric functions at each angle, and express the answer in simplest radical form?
See if you can find a pattern for the coordinates. Use this to evaluate the trigonometric functions without using the sketch.
