Question
Integrate the function: $\frac{\sqrt{\tan x}}{\sin x \cos x}$

Answer

Let $I=\int \frac{\sqrt{\tan x}}{\sin x \cos x}$ 
$=\int \frac{\sqrt{\tan x} \cdot \cos x}{\sin x \cos x \cdot \cos x} d x$ 
$= \int \frac{\sqrt{\tan x}}{\tan x \cos ^{2} x} d x$ 
$= \int \frac{\sec ^{2} x d x}{\sqrt{\tan x}}$ 
Let $\tan x = t $
$\Rightarrow \sec^2x\ dx = dt$
$\Rightarrow I=\int \frac{d t}{\sqrt{t}}$
$=2 \sqrt{t}+C$
$=2 \sqrt{\tan x}+c$
