How to solve adjoint
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]. WebTo find the adjoint of a matrix, first replace each element in the matrix by its cofactor and then transpose the matrix. Remember that the formula to compute the i, j cofactor of a matrix is as follows: Where M ij is the i, j minor of the matrix, that is, the determinant that results from deleting the i-th row and the j-th column of the matrix.
