Let A, B and C be matrices such that the following operations are defined. Let A and tr(A) denote the transpose and trace of A respectively. Let I and O denote identity and zero matrices respectively. For each of the following statements, determine whether it is True or False. If it is True, prove it. If it is False, give a counter example to disprove it. Four or five randomly selected statements will be (1) If AB=O, then A= O or B=0. (2) If A²= I, then A= I or A=-1. (3) AB BA
