Consider the matrix A =
3
4. Show that p(A)v = p(c)v holds in general, if v is an eigenvector of A for the eigenvalue c.
5. Assume now that v1, v2, ..., Un are eigenvectors to different eigenvalues c1, C2, ..., Cn. We want to show that these eigenvectors are linearly indepdendent. To do so, write down a
linear combination of the form v = bv1 + bzvzt... +bn Un = 0 and show that all coefficient by are zero. To show, for example, that bị is zero, you can consider the polynomial
P1 (z) = (z – c2)(r – c3)... (z - Cn) and evalutate pi (A)v.
