Exercise 7.2.7 Suppose A is an nxn matrix and let V be an eigenvector such that AV = V. Also suppose
the characteristic polynomial of A is
det (x1 - A)=x"+an_1x². ++a₁x+ao
Explain why
(A"+an-1An-1
++ a₁A+aol) V = 0
If A is diagonalizable, give a proof of the Cayley Hamilton theorem based on this. This theorem says A
satisfies its characteristic equation,
A" +an-14"-1.
++a₁A+aol = 0
