Not all 2× 2 matrices have an inverse matrix. If the determinant of the matrix is zero, then it will not have an inverse; the matrix is then said to be singular. Only non-singular matrices have inverses. Asimpleformulafortheinverse In the case of a 2×2 matrix A = a b c d! a simple formula exists to ﬁnd its inverse: if A = a b c d! then A−1 = 1 ad−bc d −b −c a!
