Question

Matrix A = (2 x 2)

Row 1 is:  3/4   -1/4

row 2 is:  -1/4    3/4

(ii) Determine the eigenvalues and eigenvectors of A. (May you please describe in depth

(iii) What are the algebraic and geometric multiplicities of each eigenvalue? Is A diagonalizable and if so, what is the diagonalization (i.e., D and P)?

(iv) Assume that the above A corresponds to the dynamical system xk = Axk-1 with xk = (2 x 1)

row 1 is:  1

Row 2 is: 2

Determine the x10 

What is the steady-state of this dynamical system? (May you please describe in depth

 

Problem 5

Let 

\[
\mathbf{A} = \begin{pmatrix} \frac{3}{4} & -\frac{1}{4} \\ -\frac{1}{4} & \frac{3}{4} \end{pmatrix}.
\]

(i) What is the characteristic polynomial of \(\mathbf{A}\)?

(ii) Determine the eigenvalues and eigenvectors of \(\mathbf{A}\).

(iii) What are the algebraic and geometric multiplicities of each eigenvalue? Is \(\mathbf{A}\) diagonalizable and if so, what is the diagonalization (i.e., \(\mathbf{D}\) and \(\mathbf{P}\))?

(iv) Assume that the above \(\mathbf{A}\) corresponds to the dynamical system 

\[
\mathbf{x}^{k} = \mathbf{A}\mathbf{x}^{k-1}
\]

with \(\mathbf{x}^0 = \begin{pmatrix} 1 \\ 2 \end{pmatrix}\).

Determine the \(\mathbf{x}^{10}\). What is the steady-state of this dynamical system?
