The adjoint of a square matrix A = [a ij] n×n is defined as the transpose of the matrix [A ij] n×n , where A ij is the cofactor of the element a ij.

Here, a 12 = Element of the first row and second column = –3. M 12 = Minor of a 12.

Sep 19, 2023 · We have to input the numbers given by our matrix under the correct symbols from the picture. For example, a_3 a3 is in the first row in the third column, so we find the corresponding cell in our matrix and check that it has 5 5 in there. Therefore, we put a_3 = 5 a3 = 5 into the inverse matrix calculator.
