Question
![**Title: Solving Differential Equations Using Undetermined Coefficients and Superposition**
---
**Objective:**
Analyze the applicability of the method of undetermined coefficients together with superposition to find a particular solution of the given differential equation.
---
**Problem Statement:**
Decide whether the method of undetermined coefficients together with superposition can be applied to find a particular solution of the given equation. Do not solve the equation.
\[ y'' + 5y' + 8y = e^{3t} + 7 \]
---
**Multiple Choice Question:**
Can the method of undetermined coefficients together with superposition be applied to find a particular solution of the given equation?
- **A.** No, because the differential equation does not have constant coefficients.
- **B.** Yes
- **C.** No, because the right side of the given equation is not the correct type of function.
- **D.** No, because the differential equation is not linear.
---
**Discussion:**
To determine the correct approach, consider the following:
1. **Constant Coefficients:** The method of undetermined coefficients requires the differential equation to have constant coefficients. Check if the coefficients of \( y'', y', \) and \( y \) are constant.
2. **Type of Function:** The method is typically used when the non-homogeneous term (right side) is an exponential, polynomial, sine, or cosine function. Evaluate if \( e^{3t} + 7 \) fits these criteria.
3. **Linearity:** Ensure the differential equation is linear. A differential equation is linear if it can be written in the form:
\[ a_n(t)y^{(n)} + a_{n-1}(t)y^{(n-1)} + \ldots + a_1(t)y' + a_0(t)y = g(t) \]
where \( a_i(t) \) and \( g(t) \) are given functions.
By understanding these conditions, you can decide the most appropriate answer to the question presented.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa827acfe-a0bc-46c0-ab61-62657df3b5db%2F596e2b6a-87a7-439d-bab6-9dd0337b768d%2Fiugx4dp_processed.png&w=3840&q=75)
