![**Finding Eigenvalues and Eigenfunctions of a Boundary-Value Problem**
For the given boundary-value problem, we will determine the eigenvalues \( \lambda \) and eigenfunctions \( y(x) \) ensuring that each value of \( k \) corresponds to two unique eigenvalues.
The differential equation and boundary conditions are given by:
\[ y'' + \lambda y = 0 \]
\[ y(-\pi) = 0, \quad y(\pi) = 0 \]
We need to find the following expressions in terms of \( k \):
**1. Eigenvalues \( \lambda_{2k-1} \):**
\[ \lambda_{2k-1} = \]
**2. Eigenfunctions \( y_{2k-1}(x) \):**
\[ y_{2k-1}(x) = \]
\( k = 1, 2, 3, \ldots \)
**3. Eigenvalues \( \lambda_{2k} \):**
\[ \lambda_{2k} = \]
\( k = 1, 2, 3, \ldots \)
**4. Eigenfunctions \( y_{2k}(x) \):**
\[ y_{2k}(x) = \]
\( k = 1, 2, 3, \ldots \)
This problem requires solving a second-order linear homogeneous differential equation with specified boundary conditions, leading to a set of eigenvalues and corresponding eigenfunctions which satisfy both the differential equation and boundary conditions.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8ef76dc7-4187-4f97-9d11-35100314604d%2F03aaff19-57f6-4e80-889f-6c22a44b758a%2Fo9ugoln_processed.jpeg&w=3840&q=75)
