If $$\frac{{\tan \theta + \sin \theta }}{{\tan \theta - \sin \theta }} = \frac{{{\text{k}} + 1}}{{{\text{k}} - 1}},$$ then k = ?
A. cosecθ
B. secθ
C. cosθ
D. sinθ
Answer: Option B
Solution (By Examveda Team)
$$\eqalign{ & \frac{{\tan \theta + \sin \theta }}{{\tan \theta - \sin \theta }} = \frac{{{\text{k}} + 1}}{{{\text{k}} - 1}} \cr & \frac{{\tan \theta }}{{\sin \theta }} = {\text{k}} \cr & {\text{k}} = \sec \theta \cr} $$This Question Belongs to Arithmetic Ability >> Trigonometry
