True or False. You do not need to show any work or justify your answers for this question An under determined system of linear equation is always consistent. (b) For two n x n matrices A, B, det(AB) = det(BA). (c) If u and u2 are unit vectors in an inner product space, then the scalar pro- jection of u, onto uz and the scalar projection of u2 onto u, are equal. (d) If u, v are two vectors in an inner product space with (u, v) = 0, then u and v are linearly independent. Similar matrices have the same characteristic equation. (f). If A is a diagonalizable square matrix, then A is also diagonalizable.
