Question
![Let \( A \) be a \( 3 \times 3 \) matrix with distinct eigenvalues \(\lambda_1, \lambda_2, \lambda_3\), and let \(\mathbf{v_1}, \mathbf{v_2}, \mathbf{v_3}\) be corresponding eigenvectors, respectively. \(\mathcal{B} = \{\mathbf{v_1}, \mathbf{v_2}, \mathbf{v_3}\}\) is a linearly independent set, and is therefore a basis for \(\mathbb{R}^3\).
**(a)** Let \(\mathbf{x}\) be a vector in \(\mathbb{R}^3\) such that
\[
[\mathbf{x}]_{\mathcal{B}} = \begin{bmatrix} a \\ b \\ c \end{bmatrix}
\]
Compute \(A\mathbf{x}, A^2\mathbf{x}, \text{ and } A^{34}\mathbf{x} \) in terms of \(\lambda_1, \lambda_2, \lambda_3, \mathbf{v_1}, \mathbf{v_2}, \mathbf{v_3}, a, b, \text{ and } c\) only.
**(b)** Suppose that \(\lambda_1 = 1\), \(|\lambda_2| < 1\), and \(|\lambda_3| < 1\). Compute the expression below, and explain your reasoning clearly.
\[
\lim_{k \to \infty} A^k \mathbf{x}
