WebJul 15, 2024 · 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. In other words, the transpose of a cofactor matrix of the square matrix … WebRemember that for a matrix to be invertible it's reduced echelon form must be that of the identity matrix. When we put this matrix in reduced echelon form, we found that one of the steps was to divide each member of the matrix by the determinant, so if the determinant is 0, we cannot do that division, and therefore we cannot put the matrix in the form of the …

WebMina. 6 years ago. What Sal introduced here in this video, is a method that was 'woven' specially for finding inverse of a 2x2 matrix but it comes from a more general formula for determining inverse of any nxn matrix A which is: A⁻¹ = 1/det (A) * adj (A) where adj (A) - adjugate of A - is just the transpose of cofactor matrix Cᵀ.
