WebAn eigenvector of A is a vector that is taken to a multiple of itself by the matrix transformation T (x)= Ax, which perhaps explains the terminology. On the other hand, “eigen” is often translated as “characteristic”; we may think of an eigenvector as describing an intrinsic, or characteristic, property of A. Note Webif v is an eigenvector of A with eigenvalue λ, Av = λv. I Recall: eigenvalues of A is given by characteristic equation det(A−λI) which has solutions λ1 = τ + p τ2 −44 2, λ2 = τ − p τ2 −44 2 where τ = trace(A) = a+d and 4 = det(A) = ad−bc. I If λ1 6= λ2 (typical situation), eigenvectors its v1 and v2 are linear independent ...
