Determinants possess many algebraic properties, including that the determinant of a product of matrices is equal to the product of determinants. Special types of matrices have special determinants; for example, the determinant of an orthogonal matrix is always plus or minus one, and the determinant of a complex Hermitian matrix is always real . The proofs of these properties are given at the end of this section. Remark The main use of P2 is that it enables us to factor a common multiple of the entries of a particular row out of the determinant.
