Draw a unit circle. Label the angles 0, /6, /4, /3, . . . , 7/4, 11/6,

Draw a unit circle. Label the angles 0, π/6, π/4, π/3, . . . , 7π/4, 11π/6, 2π and the coordinates of the points on the unit circle that correspond to each of these angles. Explain how symmetry can be used to find the coordinates of points on the unit circle for angles whose terminal sides are in quadrants II, III, and IV.
