Diagonalization provides an alternative method for computing the exponential of a complete matrix.
(a) First show that if
D = diag(d1,... ,dn)
is a diagonal matrix, so is
etD = diag(etd1........etdn).
(b) When possible, use diagonalization to compute the exponentials of the matrices in Exercises 9.4.1-2.
