(2) Compute the determinant of A, denoted det(A) and the trace of A, denoted tr(A).

Expert Solution

Step 1: Introduction

Given information:

The matrix $A equals open square brackets table row 2 cell negative 3 end cell 1 row 1 cell negative 2 end cell 1 row 1 cell negative 3 end cell 2 end table close square brackets$ .

To find:

(1) The eigenvalues of the matrix $A$ and the corresponding eigenvectors.

(2) The determinant of $A$ and the trace of $A$ .

Concept used:

Eigenvalues and eigenvectors of a matrix are values and vectors (v) that satisfy the equation $A v space equals space lambda v$ , where $A$ is the matrix.

Formula used:

To find eigenvalues, the characteristic equation is used, which is $d e t left parenthesis A space minus space lambda I right parenthesis space equals space 0$ , where $I$ is the identity matrix. The eigenvalues are the solutions to this equation.
To find eigenvectors, the system of equations $left parenthesis A space minus space lambda I right parenthesis v space equals space 0$ is solved for each eigenvalue. The eigenvectors are the solutions to this system of equations.
