Text Solution

AI Generated Solution

To compute \( \tan(22.5^\circ) \), we can use the half-angle formula for tangent. Here’s a step-by-step solution: ### Step 1: Identify the angle We know that \( 22.5^\circ \) is half of \( 45^\circ \). Thus, we can set: \[ a = 22.5^\circ \quad \text{and} \quad 2a = 45^\circ \] ...
