Consider a vector space Mx2 (R) and a norm on the vector space defined as ||A|| = max{a11 + a21, |a12+ a22]}, all a12 where A Mx2 (R). a21 a22 X 3 x Y [2] -3 y matrix i.e. BBT = BTB I and assume = Let B x, y > 0. Then find the norm of the matrix C = = [VA [4x 4x Ay be an orthogonal [2] (i.e., ||C||) Ay
