= 4. Let A be a square matrix of order n, where I+A is invertible. Complete the following problems. (a) Show that (I – A) (I + A)-1 = (I + A)-1 (I – A). (5 marks) (b) Show that if A skew-symmetric then (I – A) (I + A)-- is orthogonal. (5 marks) (c) Show that if A is orthogonal then (I – A) (I + A)-1 is skew-symmetric. (5 marks) -1
