Question : $\sqrt{\frac{1+\sin A}{1-\sin A}}=$_______.
Option 1: $\operatorname{coesc} A-\cot A$
Option 2: $\sec A-\tan A$
Option 3: $\sec A+\tan A$
Option 4: $\sec A$
Correct Answer: $\sec A+\tan A$
Solution : $\sqrt{\frac{1+\sin A}{1-\sin A}}$ $=\sqrt{\frac{1+\sin A}{1-\sin A}\times\frac{1+\sin A}{1+\sin A}}$ $=\sqrt{\frac{(1+\sin A)^2}{(1+\sin A)(1-\sin A)}}$ $=\sqrt{\frac{(1+\sin A)^2}{(1-\sin^2 A)}}$ $=\sqrt{\frac{(1+\sin A)^2}{(\cos^2 A)}}$ $=\frac{1+\sin A}{\cos A}$ $=\frac{1}{\cos A}+\frac{\sin A}{\cos A}$ $=\sec A+\tan A$ Hence, the correct answer is $\sec A+\tan A$.
