?When Shortcut Fails The eigenvector shortcut of may fail when b = 0, forcing a return

Chapter 5, Problem 18

(choose chapter or problem)

When Shortcut Fails The eigenvector shortcut of Problem 17 may fail when b = 0, forcing a return to the definition \(A \bar{v}=\lambda \bar{v}\) to find the eigenvector(s). For each eigenvalue in the following matrices, find the eigenvector(s). Discuss how/why the shortcut fails and why the definition succeeds.

(a) \(\left[\begin{array}{ll} 3 & 0 \\ 5 & 3 \end{array}\right]\)

(b) \(\left[\begin{array}{ll} 3 & 0 \\ 5 & 2 \end{array}\right]\)

(c) \(\left[\begin{array}{ll} 3 & 0 \\ 0 & 3 \end{array}\right]\)
