(i) ifA=[{:(1,-4),(3,1):}]and b=[{:(1,0,5),(-2,4,3):}],then show that : (AB)'=B'A' implies(1)/(2)(A-A')=[{:(0,3//2,-4),(-3//2,0,7//2),(4,-7//2,0):}] Now A=(1)/(2)(A+A')+(1)/(2)(A-A') implies[{:(2,0,-4),(-3,1,5),(4,-2,3):}]=[{:(2,-3//2,0),(-3//2,1,3//2),(0,3//2,3):}]+[{:(0,3//2,-4),(-3//2,0,7//2),(4,-7//2,0):}](ii) if A=[{:(2,3),(0,1):}]and B=[{:(3,4),(2,1):}],then prove that : (AB)'=B'A' |
