Find (a) the characteristic equation, (b) the eigenvalues, and (c) the corresponding eigenvectors of the matrix. $$\left[\begin{array}{ll} 3 & -1 \\ 5 & -3 \end{array}\right]$$
Find (a) the characteristic equation, (b) the eigenvalues, and (c) the corresponding eigenvectors of the matrix. $$\left[\begin{array}{rr} -2 & 4 \\ 2 & 5 \end{array}\right]$$
Find the area of the triangle having the given vertices. $$(-1,2),(2,2),(-2,4)$$
Use a graphing utility or computer software program with matrix capabilities to find the eigenvalues of the matrix. Then find the corresponding eigenvectors. $$\left[\begin{array}{rrr} 4 & 0 & 0 \\ 0 & 0 & -3 \\ 0 & -2 & 1 \end{array}\right]$$
Verify that \(\lambda_{i}\) is an eigenvalue of \(A\) and that \(\mathbf{x}_{i}\) is a corresponding eigenvector. $$\begin{array}{l} A=\left[\begin{array}{ll} 1 & 2 \\ 0 & -3 \end{array}\right] ; \quad \lambda_{1}=1, \quad \mathbf{x}_{1}=\left[\begin{array}{l} 1 \\ 0 \end{array}\right] \\ \lambda_{2}=-3, \quad \mathbf{x}_{2}=\left[\begin{array}{r} -1 \\ 2 \end{array}\right] \end{array}$$
