I need help proving the identity of the statement and the rule

### Proving the Trigonometric Identity

#### Objective:
Prove the following trigonometric identity:
\[ \tan(2\pi - x) = -\tan(x) \]

#### Instructions:
Each statement in your proof must be based on a Rule selected from the Rule menu. For additional details about a Rule, select the "More Information" button on the right of the Rule.

#### Steps:

1. **Statement and Rule Interface:**
   - **Statement:**
     \[ \tan(2\pi - x) \]
   - **Rule:** Select an appropriate trigonometric rule from the drop-down menu.

2. **Interface Options:**
   - The interface provides a list of trigonometric functions and constants for rule selection.
   - Available functions include:
     \[ \cos, \sin, \tan, \cot, \sec, \csc \]
   - Available constants and symbols include:
     \[ \pi, (), \frac{}{} \]

3. **Validation:**
   - After formulating the statement and selecting the rule, click the "Validate" button to check your work.

---

#### Proof Outline:
To prove the identity, use the periodic properties of the tangent function, along with the identities for sine and cosine. Consider exploring:
1. The periodicity of the tangent function.
2. The angle subtraction formulas for sine and cosine.

By systematically applying these rules, you can demonstrate that:
\[ \tan(2\pi - x) = \frac{\sin(2\pi - x)}{\cos(2\pi - x)} = -\tan(x) \]

This interactive proof exercise allows students to understand the underlying principles and visually explore the rules governing trigonometric identities.
