Find the principal value of: `cot^(-1)(sqrt(3))`

Explanation

To find the principal value of \( \cot^{-1}(\sqrt{3}) \), we can follow these steps:

### Step 1: Set up the equation
Let \( x = \cot^{-1}(\sqrt{3}) \). This means that \( \cot(x) = \sqrt{3} \).

### Step 2: Identify the angle
We need to find the angle \( x \) such that \( \cot(x) = \sqrt{3} \). We know that:
\[
