Math Problem Solver

You are given two unit circles: Circle A and circle B. Notice that each quadrant is

90◦

and in circle A, the angle in each quadrant bisects the quadrant in which it

exists. Nevertheless, in circle B, the angles in each quadrant trisect the quadrant

in which they exist.

NOTE: The angles should increase by the same angle measure around the entire

circle.

(a) For each circle, write in the angle measures in both radians and

degrees for all angles. Be sure to label the angles in counterclockwise

direction, starting with 0

◦=0 radians as the positive x-axis.

(b) Use the equation for the unit circle to show that circles centered at

the origin are symmetric about the x-axis, y-axis and the origin.

Question Two

With graphical demonstration, clearly explain how the unit circle relates to speci
