Question
![**Proving Trigonometric Identities Using Double-Angle Properties**
**Objective:**
Prove the identity:
\[
\frac{1 + \tan^2 x}{1 - \tan^2 x} = \sec 2x
\]
**Instructions:**
Note that each statement must be based on a rule chosen from the Rule menu. To see a detailed description of a rule, select the More Information button to the right of the rule.
**Steps:**
1. **Statement:**
\[
\frac{1 + \tan^2 x}{1 - \tan^2 x}
\]
2. **Transformation using Pythagorean Identity:**
This step involves transforming the left-hand side of the equation using the Pythagorean identity:
\[
\sec^2 x = 1 + \tan^2 x
\]
The transformed statement:
\[
\frac{\sec^2 x}{1 - \tan^2 x}
\]
*Selected Rule:* Pythagorean
3. **Further Simplification or Rule Application Required:**
The next step should continue to simplify or transform the expression to match the right-hand side (\(\sec 2x\)) using relevant algebraic identities or rules. However, the line indicates an error which implies that further modification is needed.
**Validation:**
The current transformation is incorrect. Select the appropriate rules to continue proving the identity.
**Additional Tools:**
- A palette of trigonometric identities and symbols is available for use.
- Validation button indicates if the current transformation is correct or requires adjustment.
**Summary:**
Continue applying algebraic and trigonometric identities to correct and complete the proof.
