Solution
Expression : $$\sqrt{[\frac{(1 + sinA)}{(1 - sinA)}}]$$
Multiplying both numerator and denominator by $$(\sqrt{1+sinA})$$
= $$\sqrt{[\frac{(1 + sinA)}{(1 - sinA)}}]$$ $$\times \sqrt{\frac{(1+sinA)}{(1+sinA)}}$$
= $$\sqrt{\frac{(1+sinA)^2}{1-sin^2A}} = \sqrt{\frac{(1+sinA)^2}{cos^2A}}$$
= $$\frac{1+sinA}{cosA} = (\frac{1}{cosA}+\frac{sinA}{cosA})$$
= $$secA+tanA$$
=> Ans - (C)
