To calculate the determinant of a 3 × 3 matrix, we can use the method of cofactor expansion by choosing a specific row or column of the matrix, calculating the minors for each entry of that row or …Basically, the cofactor is either M ij or M ij where the sign depends on the location of the element in the matrix. For that reason, it is easier to know the pattern of cofactors instead of actually remembering the formula. If you start in the position corresponding to a 11 with a positive sign, the sign of the cofactor has an alternating pattern.Get the free "4x4 Determinant calculator" widget for your website, blog, Wordpress, Blogger, or iGoogle.
