WebThe eigenvalues of A are the roots of the characteristic polynomial p ( λ) = det ( A – λ I). For each eigenvalue λ, we find eigenvectors v = [ v 1 v 2 ⋮ v n] by solving the linear system ( A – λ I) v = 0. The set of all vectors v satisfying A v = λ v is called the eigenspace of A corresponding to λ. [ I’m ready to take the quiz. http://web.mit.edu/18.06/www/Fall07/pset7-soln.pdf
