WebSep 16, 2024 · Theorem 3.2. 1: Switching Rows. Let A be an n × n matrix and let B be a matrix which results from switching two rows of A. Then det ( B) = − det ( A). When we switch two rows of a matrix, the determinant is multiplied by − 1. Consider the following example. Example 3.2. 1: Switching Two Rows. WebIt is given by det (adj (A))= (det (A))^ (n-1) where n is the order of the matrix. So here since in the question, the order is 3, det (adj (A))= (det (A))^2. Find the determinant of the …

WebJan 13, 2024 · Step 2: Next, compute the cofactors of all elements and build the cofactor matrix by substituting the elements of A with their respective cofactors. Step 3: Take the transpose of A’s cofactor matrix to find its adjoint (written as adj A). Step 4: Multiply adj A by the reciprocal of the determinant of A. WebOct 14, 2024 · The relationship between a matrix A, its adjugate matrix Adj (A) and its determinant det (A) is given by. where I is the identity matrix (in our case, it is 3 x 3). The determinant function satisfies det (B*C) = det (B) * det (C) for all square matrices B and C of the same dimensions.
