Find inverse of determinant

WebThe determinant of matrix A is denoted as ad-bc, and the value of the determinant should not be zero in order for the inverse matrix of A to exist.A simple formula can be used to calculate the inverse of a 2×2 matrix. Furthermore, in order to obtain the inverse of a 3×3 matrix, we must first determine the determinant and adjoint of the matrix. WebOne reason for this is that determinants are to do with the inverse of a matrix (that is, the inverse of a matrix A is a matrix B such that AB = BA = I, for the appropriate identity matrix I). The equation AB = BA cannot exist for a non-square matrix because the rules of matrix multiplication would require the two B's to be of different sizes.
