Contributor; We now know that the determinant of a matrix is non-zero if and only if that matrix is invertible. We also know that the determinant is a \(\textit{multiplicative}\) function, in the sense that \(\det (MN)=\det M \det N\).
Let A be the 2 x 2 matrix and is given by: Then, the adjoint of this matrix is: Here, A11 = Cofactor of a11 A12 = Cofactor of a12 A21 = Cofactor of a21 A22 = Cofactor of a22 Alternatively, the adj A can also be calculated by interchanging a11 and a22 and by changing signs of a12 and a21.
