given that the cos0=0, find the coordinates of the point where the terminal side of 0 intersects the unit circle, if 0 is a reflex angle.
(0,-1)
(0,1)
(-1,0)
(1,0)
If cos(θ) = 0, then θ is a right angle or a straight angle because the cosine of a right angle is equal to 0.
However, since the question states that θ is a reflex angle, we can determine that θ is actually a straight angle (180 degrees) and not a right angle (90 degrees).
On the unit circle, the point where the terminal side of the straight angle (180 degrees) intersects will be (-1, 0). Therefore, the correct answer is (-1, 0).
