Let A be the angle between the positive x-axis and the ray pictured. If cos(A) = and sin(A) = 1³, 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?
