WebJul 24, 2016 · A = [ 0 1 0 1] and [ 1 1 0 0]. Then we compute A B = [ 0 1 0 1] [ 1 1 0 0] = [ 0 0 0 0] = O. Thus the matrix product A B is the 2 × 2 zero matrix O. On the other hand, we compute B A = [ 1 1 0 0] [ 0 1 0 1] = [ 0 2 0 0]. Thus the matrix product B A is not the zero matrix. Therefore the statement is not true in general. Click here if solved 71 Tweet WebProof: Suppose S,T are linear operators on V such that ST is an isomorphism. Let β = {β 1,β 2,...,β n} be an ordered basis for V. Let A and B be the matrix representation of S and T, respectively, using β: A = [S] β, B = [T] β. Then [ST] β = AB. Since ST is an isomorphism, AB is an invertible matrix. By part (a), both A and B are ...

Your assignment is to prove that from A B = 0 it follows that one among A and B is singular. Now, if A is invertible, then A B = 0 implies B = A − 1 A B = A − 1 0 = 0, so B is certainly singular.
