Consider a ray drawn in the first quadrant as pictured below.
Let A be the angle between the positive x-axis and the ray pictured. If cos(A) = and sin(A) =
what is the point of intersection between the ray and the unit circle?
Reflect the ray across the y-axis into the 2nd quadrant. Let B be the angle between the positive x-axis and this new ray in the 2nd quadrant. What are the coordinates of intersection of this ray with angle B
and the unit circle?
Reflect the original ray across the origin (i.e, about the x-axis and then again about the y-axis) into the 3rd quadrant. Let C be the angle between the positive x-axis and this new ray in the 3rd quadrant.
What are the coordinates of intersection of this ray with angle C and the unit circle?
Reflect the original ray across the x-axis into the 4th quadrant. Let D be the angle between the positive x-axis and this new ray in the 4th quadrant. What are the coordinates of intersection of this ray with
angle D and the unit circle?
