Please help to solve these questions

(d) If A is diagonalizable, diagonalize A, i.e., find an invertible matrix P and a diagonal matrix D such that A = PDP-1. You do NOT need to calculate P-1. (e) Is A unitarily diagonalizable? Explain. (f) If A is unitarily diagonalizable, unitarily diagonalize A, i.e., find a unitary matrix U and a diagonal matrix D such that A = UDU*. You do NOT need to calculate U*
