If $$\frac{{\tan \theta + \sin \theta }}{{\tan \theta - \sin \theta }} = \frac{{{\text{k}} + 1}}{{{\text{k}} - 1}},$$ then k = ?
Answer & Solution
Correct Answer:
Option
B
$$\eqalign{
& \frac{{\tan \theta + \sin \theta }}{{\tan \theta - \sin \theta }} = \frac{{{\text{k}} + 1}}{{{\text{k}} - 1}} \cr
& \frac{{\tan \theta }}{{\sin \theta }} = {\text{k}} \cr
& {\text{k}} = \sec \theta \cr} $$
