**Trigonometric Functions: Problem Example**

**Problem Statement:**
Express the given trigonometric function as a function of a different angle, where \(0 \leq \theta < 360\).

\[ \sin(191^\circ) \]

**Interactive Solution Input:**
\[ \sin(\text{[ ]}) \]

**Explanation:**
Given the angle \(191^\circ\), we need to express \( \sin(191^\circ) \) as a sine function of a different angle within the range \(0^\circ\) to \(360^\circ\).

To do this, consider the properties of the sine function and how it behaves with respect to angle transformations.

**Key Concepts:**
- Understanding sine function transformations and symmetry properties
- Knowing how to find equivalent angles using periodicity and reference angles

**Instructions:**
1. Determine if the angle can be transformed within the given range by adding or subtracting \(180^\circ\) or \(360^\circ\) if necessary.
2. Check for sine function properties such as \(\sin(\theta + 180^\circ) = -\sin(\theta)\).
3. Input the equivalent angle into the provided answer box.

**Note:**
This exercise aims to solidify your grasp of trigonometric identities and transformations. 

**Hint:**
Since \( \sin \) is periodic with a period of \(360^\circ\), angles that differ by multiples of \(360^\circ\) have the same sine value, and angles related by \(180^\circ\) will have the same absolute sine value but maybe a different sign.

For example, angles in the second and third quadrants can be transformed to corresponding angles in the first quadrant for simplification.

Good luck!
