Question 1084471: An equilateral triangle's vertices lie on the unit circle, which is is placed on an xy plane.
In Quadrant 1, point P(0.5, 0.866) is given, while one of the vertices lie on the x-axis
(between Quadrant 3 and 5). Determine the exact value of the trigonometric ratios at
each vertex Answer by ikleyn(52851) (Show Source):
1. The point P is not relevant to the question.
2. Quadrant 5 DOES NOT EXIST in the nature.
3. The interior angles of an equilateral triangle are all 60 degrees.
4. sin(60) = . cos(60) = .
