What is greater, `tan1 or tan^(-1)1?`

Explanation

To determine which value is greater between \( \tan(1) \) and \( \tan^{-1}(1) \), we can follow these steps:

### Step 1: Understand the values
We know that \( \tan^{-1}(1) \) is the angle whose tangent is 1. The angle for which the tangent is 1 is \( \frac{\pi}{4} \) radians (or 45 degrees). Therefore, we can write:
\[ \tan^{-1}(1) = \frac{\pi}{4} \]
