1. Write the equation of the unit circle : On the graph of the unit circle shown: 2. Plot all points on the unit circle with x-coordinate x = +; label these points A, B, C, D. (-1,0) (0,1) (0,-1) 3 3. Use the equation of the unit circle to compute the y-coordinates of A, B, C, D; write these y-coordinates as fractions. 4. Label the points A, B, C, D with their coordinates, as an ordered pair (x,y). 0 (1,0)'
