Write `tan^(-1) x, x gt 0` in the form of other inverse trigonometric function

Explanation

To express \( \tan^{-1} x \) (where \( x > 0 \)) in terms of other inverse trigonometric functions, we can follow these steps:

### Step 1: Set up the relationship
Let \( \theta = \tan^{-1} x \). By the definition of the inverse tangent function, we have:
\[ \tan \theta = x \]
