Determine whether the matrices are inverses
WebFinal answer. Determine whether the given matrices are inverses of each other by computing their product. Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or simplified fraction for each matrix element.) A. The given matrices are inverses of each other because their product is the matrix B ... WebThe inverse of a 3x3 matrix A is calculated using the formula A-1 = (adj A)/(det A), where. adj A = The adjoint matrix of A; det A = determinant of A; det A is in the denominator in the formula of A-1.Thus, for A-1 to exist det A should not be 0. i.e.,. A-1 exists when det A ≠ 0 (i.e., when A is nonsingular); A-1 does not exist when det A = 0 (i.e., when A is singular)
