Transcribed Image Text:**Problem 8: Differential Equation Exploration**
Objective: Demonstrate that the function \( y = e^x (\sin 2x + \cos 2x) \) satisfies the differential equation \( y'' - 2y' + 5y = 0 \).
### Approach:
1. **Identify the Function:**
- Given: \( y = e^x (\sin 2x + \cos 2x) \)
2. **Compute Derivatives:**
- First derivative, \( y' \)
- Second derivative, \( y'' \)
3. **Substitute into the Differential Equation:**
- Plug \( y \), \( y' \), and \( y'' \) into \( y'' - 2y' + 5y = 0 \)
4. **Verify Solution:**
- Simplify the expression to confirm the equation equals zero.
### Explanation:
This exercise involves calculus techniques: differentiation and verification by substitution. By following these steps, you validate that the given function is indeed a solution to the specified differential equation.
