WebWe have also seen that the determinant of a triangular matrix C is just the product of the elements on the diagonal. This tells us that the determinant of the identity matrix I is det(I) = 1. And this leads to a sometimes-useful result: Any invertible matrix A has an inverse matrix A −1 such that (A)(A −1) = (A −1)(A) = I. Webthe matrix A(2) or A(1), and obtain the determinant value. This technology was This technology was even used to nd the inverse of a tridiagonal matrix in [3, 8].
