Find eigan values and eigan vectors
Solution
The sequence you provided appears to represent a matrix. If you intended this sequence as a 3x3 matrix, it could be interpreted as follows:
1 & 1 & 3 \\ 1 & 5 & 1 \\ 3 & 1 & 1 \end{pmatrix}$$ To find the eigenvalues and eigenvectors, we proceed with the following steps: ### 1. Eigenvalues: The eigenvalues $$\lambda$$ of matrix $$\mathbf{A}$$ are found by solving the characteristic equation: $$\text{det}(\mathbf{A} - \lambda \mathbf{I}) = 0$$ Where $$\mathbf{I}$$ is the identity matrix of the same size as $$\mathbf{A}$$. ### 2. Eigenvectors: For each eigenvalue $$\lambda$$, the corresponding eigenvector $$\mathbf{v}$$ is found by solving the equation: $$(\mathbf{A} - \lambda \mathbf{I})\mathbf{v} = \mathbf{0}$$ Let's compute the eigenvalues and eigenvectors.The eigenvalues and corresponding eigenvectors of the matrix $$\mathbf{A}$$ are as follows: ### Eigenvalues: $$\lambda_1 = -2, \quad \lambda_2 = 3, \quad \lambda_3 = 6$$ ### Eigenvectors: - For $$\lambda_1 = -2$$, the eigenvector is: $$\mathbf{v}_1 = \begin{pmatrix} 0.7071 \\ 0 \\ -0.7071 \end{pmatrix}$$ - For $$\lambda_2 = 3$$, the eigenvector is: $$\mathbf{v}_2 = \begin{pmatrix} -0.5774 \\ 0.5774 \\ -0.5774 \end{pmatrix}$$ - For $$\lambda_3 = 6$$, the eigenvector is: $$\mathbf{v}_3 = \begin{pmatrix} -0.4082 \\ -0.8165 \\ -0.4082 \end{pmatrix}$$ Would you like more details or have any questions? ### Related Questions: 1.
