The trigonometric ratio which is positive in the fourth quadrant is:
Cosine.
Tangent.
Cosecant.
Sine.
Given that sin x = 3/5 ,then tan x is:
3/5.
3/4.
4/5.
4/3.
The relationship that exists between sin θ, cos θ and tan θ is:
tan θ = sin θ / cos θ.
tan θ = sin θ + cos θ.
tan θ = SIN θ - COS θ.
tan θ = cos θ / sin θ.
The value of sin 30° / cos 30° is:
1 / √3.
2 / √3.
√3 / 2.
√3.
The value of cos 30° is:
(√3)/2.
1/√2.
√2.
