WebIn the case of real numbers, the inverse of any real number a was the number a-1, such that a times a-1 equals 1. We knew that for a real number, the inverse of the number was the reciprocal of the number, as long as the number wasn't zero. The inverse of a square matrix A, denoted by A-1, is the matrix so that the product of A and A-1 is the identity matrix. WebHere are the steps involved in finding the adjoint of a 2x2 matrix A: Find the minor matrix M by finding minors of all elements. Find the cofactor matrix C by multiplying elements of M by (-1) row number + column number. Then the adjoint matrix is, adj (A) = C T.
