If A and B are equal, where each has rows [0,1], [0,0] then these aren't invertible, even though …

WebSince AB = I, we have det (A) det (B) = det (AB) = det (I) = 1. This implies that the determinants det (A) and det (B) are not zero. Hence A, B are invertible matrices: A − 1, B − 1 exist. Now we compute I = BB − 1 = BIB − 1 = B(AB)B − 1 since AB = I = BAI = BA. Hence we obtain BA = I. Since AB = I and BA = I, we conclude that B = A − 1.

WebAnswer (1 of 4): This is true, only as long as A and B have distinct eigenvalues. The relation is also an if and only if relation, which means that it goes both ways.

Then, A(B... local car dealerships in ctWebAB = I n then 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.
