1. Show that if λ1 and λ2 are different eigenvalues of A and u1 and u2 are associated eigenvectors, then u1 and u2 are independent. More generally, show that if λ1, ..., λk are distinct eigenvalues of A and ui is an eigenvector associated to λi for i=1, ..., k, then u1, ..., uk are independent.

2. Show that for each eigenvalue λ, the set E(λ) = {u LaTeX: \in∈Rn: u is an eigenvector associated to λ} is a subspace of Rn.

Find the two scalars (in C) λ1 and λ2 so that A − λI is singular. For A = [11 1 -1] Use the fact that A − λI is singular iff det(A − λI) = 0. For each λi find a basis for RS(A−λiI). Each basis will consist of a single vector, verify that the two vectors you found are orthogonal.
