Math Problem Statement

To find eigen vectors with solutions

Find the eigenvectors and eigenvalues of a matrix.

Solution

The eigenvalues and corresponding eigenvectors of the matrix A=(862674243)A = \begin{pmatrix} 8 & -6 & 2 \\ -6 & 7 & -4 \\ 2 & -4 & 3 \end{pmatrix} are as follows:

Eigenvalues:

  1. λ1=15\lambda_1 = 15
  2. λ2=3\lambda_2 = 3
  3. λ30\lambda_3 \approx 0 (very close to zero)

Eigenvectors (corresponding to each eigenvalue):

  1. For λ1=15\lambda_1 = 15, the eigenvector is: v1=(232313)v_1 = \begin{pmatrix} -\frac{2}{3} \\ \frac{2}{3} \\ -\frac{1}{3} \end{pmatrix}
  2. For λ2=3\lambda_2 = 3, the eigenvector is: v2=(231323)v_2 = \begin{pmatrix} \frac{2}{3} \\ \frac{1}{3} \\ -\frac{2}{3} \end{pmatrix}
  3. For λ30\lambda_3 \approx 0, the eigenvector is: v3=(132323)v_3 = \begin{pmatrix} \frac{1}{3} \\ \frac{2}{3} \\ \frac{2}{3} \end{pmatrix}
