Evaluate: `intsqrt(tanx)`dx

Explanation

To evaluate the integral \(\int \sqrt{\tan x} \, dx\), we will use a substitution method. Here’s a step-by-step solution:

### Step 1: Substitution
Let \( t = \sqrt{\tan x} \). Then, we have:
\[ t^2 = \tan x \implies \tan x = t^2 \]
Differentiating both sides with respect to \(x\):
