Let us consider, a= a −1+b −1a −1 + a … Webbthen A and B are inverses of each other. Notice that the fourth property implies that if AB = I then BA = I. The first three properties' proof are elementary, while the fourth is too advanced for this discussion. We will prove the second. Proof that (AB) -1 = B-1 A-1. By property 4, we only need to show that (AB)(B -1 A -1) = I. We have

So it becomes: =1/a×ab /b+a+ … muddy waters bar bathroom

WebbThey are equal since b1 and b2 are equal. 19. (A solution is in the text). Write B = [b1 b2 b3]. By definition, the third column of AB is Ab3. By hypothesis, b3 = b1 + b2. So Ab3 = A(b1 + b2) = Ab1 + Ab2, by a property of matrix-vector multiplication. Thus, the third column of AB is the sum of the first two columns of AB. 20. The second column ...
