$\int(\sqrt{\tan x}+\sqrt{\cot x}) d x=$
- $\sqrt{2} \operatorname{Tan}^{-1}\left(\frac{\tan x+1}{\sqrt{\tan x}}\right)+c$
- $\sqrt{2} \operatorname{Tan}^{-1}\left(\frac{\tan x-1}{\sqrt{2 \tan x}}\right)+c$
- $\frac{1}{\sqrt{2}} \operatorname{Tan}^{-1}\left(\frac{\tan x+1}{\sqrt{2} \tan x}\right)+c$
- $\frac{1}{\sqrt{2}} \operatorname{Tan}^{-1}\left(\frac{\sqrt{\tan x}-1}{\sqrt{2} \tan x}\right)+c$
