**Linear Algebra: Eigenvalues and Eigenvectors**

Let \( A = \begin{bmatrix} 1 & 5 \\ 10 & -4 \end{bmatrix} \).

(a) What is the largest eigenvalue, \(\lambda_1\), of \(A\)?

 

(b) Find a unit eigenvector, \(v_1\), for eigenvalue \(\lambda_1\).

 

(c) What is the smallest eigenvalue, \(\lambda_2\), of \(A\)?

 

(d) Find a unit eigenvector, \(v_2\), for eigenvalue \(\lambda_2\).

 

(e) Construct a matrix \(P\) such that \(A = PDP^{-1} = P \begin{bmatrix} \lambda_1 e_1 & \lambda_2 e_2 \end{bmatrix} P^{-1}\).
