\(\int_0^{\frac{\pi}{2}} \sqrt{\tan x} d x=\)
- A \(\frac{\pi}{\sqrt{2}}\)
- B \(\frac{\pi}{2}\)
- C \(\sqrt{2} \pi\)
- D \(2 \pi\)
Answer & Solution
Correct Answer
(A) \(\frac{\pi}{\sqrt{2}}\)
Step-by-step Solution
Detailed explanation
\int_0^{\frac{\pi}{2}} \sqrt{\tan x} d x = \frac{1}{2} B\left(\frac{1/2+1}{2}, \frac{-1/2+1}{2}\right) = \frac{1}{2} B\left(\frac{3}{4}, \frac{1}{4}\right) = \frac{1}{2} \frac{\Gamma\left(\frac{3}{4}\right) \Gamma\left(\frac{1}{4}\right)}{\Gamma\left(\frac{3}{4} +…
