What is sin if is in standard position, its terminal side lies in quadrant IV, and sec=√3
***
sec=√3=1/cos
cos=1/√3
sin=-√(1-cos^2)=-√(1-1/3)=-√(2/3)
none of given ans. match this solution

sec=√3_____cos θ = ____cos θ = = =
Therefore, , and
sin θ = = = , but since sin is < 0 in the 4th quadrant, we get: - sin θ = (CHOICE b.)
You can do the check!!
