उत्तर

Let  `I = int (sqrt tan x)/(sinx cos x)` dx

`= int sqrt tan x/(sin x/ cos x * cos ^2) dx`

`= int sqrt tanx/tan x * sec^2 x dx`

`I = int (tan x)^((-1)/2)* sec^2 x dx`

Put tan x = t

sec2 x dx = dt

Hence, `I = int t^((-1)/2)dt = (t ^(1/2 + 1))/(1/2 + 1) + C` 

`= 2  t^(1/2) + C`

`= 2 sqrt(tan x) + C`
