WebIn general, the inverse of a matrix A is found using the formula (adj A)/ (det A), where "adj A" is the "adjoint of A" and "det A" is the "determinant of A". But in case of a 2x2 matrix A = ⎡ ⎢⎣a b c d⎤ ⎥⎦ [ a b c d], we can find the inverse directly using the following formula. WebFor example, decrypting a coded message uses the inverse of a matrix. Determinant may be used to answer this problem. Indeed, let A be a square matrix. We know that A is …
