Find the value of `sin120^(@)`.

Explanation

To find the value of \( \sin 120^\circ \), we can follow these steps:

### Step 1: Identify the Quadrant
First, we need to determine in which quadrant the angle \( 120^\circ \) lies. Angles between \( 90^\circ \) and \( 180^\circ \) are in the second quadrant.

**Hint:** Remember that angles in the second quadrant have sine values that are positive.

### Step 2: Use the Sine Identity
