WebInverse of a Matrix. We write A-1 instead of 1 A because we don't divide by a matrix! And there are other similarities: When we multiply a number by its reciprocal we get 1: 8 × 1 8 = 1. When we multiply a matrix by its inverse we get the Identity Matrix (which is like "1" for matrices): A × A -1 = I. Web3 de jun. de 2024 · Your first equation says : ( A + 3 B) A = I. Taking determinant both the sides, you get. det ( A + 3 B) ⋅ det ( A) = 1. This implies det ( A) can never be 0, hence A …

Similarly, on multiplying B with A, we obtain the same identity matrix: It can be concluded here that AB = BA = I. Hence A -1 = B, and B is known as the inverse of A. Similarly, A can also be called an inverse of B, or B -1 = A. porsche service sidcup
