प्रश्न
State for any acute angle θ whether cos θ increases or decreases as θ increases.
विकल्प
Increases
Decreases
उत्तर
Increases
Explanation:
For acute angles, remember what cosine means: base over hypotenuse. If we increase the angle, then the hypotenuse side gets larger. That means "base/hypotenuse" gets smaller or decreases.
