The image you provided contains a series of steps related to solving a system of differential equations involving matrices, eigenvalues, and eigenvectors. Here’s a breakdown of the key points in the image:

1. Matrix A and its properties:

The system begins by defining the matrix $A$ with certain properties:

• The trace and determinant of $A$ are related to the eigenvalues $\lambda_1$ and $\lambda_2$.
• Eigenvalues $\lambda_1 = -3$ and $\lambda_2 = 2$ are calculated from the characteristic equation of the matrix $A$.

2. Eigenvalue Problem:

The image then proceeds to solve the eigenvalue problem for $A$:

• For $\lambda_1 = -3$, the corresponding eigenvector $v_1$ is found.
• For $\lambda_2 = 2$, the corresponding eigenvector $v_2$ is calculated.

3. General Solution:

The general solution to the system of differential equations involves a combination of the eigenvectors $v_1$ and $v_2$, as well as their associated exponential terms.

4. Differential System:

A system of first-order linear differential equations is given as: $\dot{x} = x + y, \quad \dot{y} = 4x + y$ The matrix form of this system is written as: $\begin{pmatrix} \dot{x} \\ \dot{y} \end{pmatrix} = \begin{pmatrix} 1 & 1 \\ 4 & 1 \end{pmatrix} \begin{pmatrix} x \\ y \end{pmatrix}$ where matrix $A$ is $\begin{pmatrix} 1 & 1 \\ 4 & 1 \end{pmatrix}$.

This analysis deals with:

• Finding eigenvalues by solving $\det(A - \lambda I) = 0$.
• Finding eigenvectors by solving $(A - \lambda I)v = 0$.
• Constructing the general solution using the exponential of eigenvalues and the associated eigenvectors.

1. How are eigenvalues and eigenvectors used to solve systems of linear differential equations?
2. Can you explain how the determinant and trace of a matrix relate to its eigenvalues?
3. What are the properties of the exponential of a matrix in the context of solving differential equations?
4. How do initial conditions affect the solution of the system of differential equations?

Tip: When solving a system of differential equations, always check the nature of the eigenvalues (real or complex) to understand the behavior of the solutions (e.g., oscillatory for complex eigenvalues).
