Verified Solution

Answer & Solution

Correct Answer

(A) \(\frac{\pi}{4}\)

Step-by-step Solution

Detailed explanation

\(\begin{aligned} & \text { Since } \int_0^{\frac{\pi}{2}} \frac{\cot ^{\mathrm{n}} x}{\tan ^{\mathrm{n}} x+\cot ^{\mathrm{n}} x} \mathrm{~d} x=\frac{\pi}{4} \\ & \int_0^{\frac{\pi}{2}} \frac{\sqrt{\cot x}}{\sqrt{\cot x}+\sqrt{\tan x}} \mathrm{~d} x=\frac{\pi}{4}\end{aligned}\)
