WebJun 25, 2024 · The matrix Adj(A) is called the adjoint matrix of A. When A is invertible, then its inverse can be obtained by the formula A − 1 = 1 det (A)Adj(A). For each of the following matrices, determine whether it is invertible, and if so, then find the invertible matrix using the above formula. (a) A = [1 5 2 0 − 1 2 0 0 1]. (b) B = [1 0 2 0 1 4 3 0 1]. WebWe can either use that formula or simply the following steps instead of the formula to find the inverse of 2x2 matrix. The steps are explained with an example where we are going to find the inverse of A = ⎡ ⎢⎣1 −1 0 2⎤ ⎥⎦ [ 1 − 1 0 2]. Step - 1: Find the det A just by cross multiplying the elements and subtracting.
