4 Let the trace function be Tr(M) = m1,1 + ... + Mn,n. Define also the sum down the other diagonal Tr* (M) = M1,n + ··· + Mn, 1. (a) Show that the two functions Tr, Tr*: Mnxn → R are linear. (b) Show that the function 0: Mnxn → R2 given by 0(M)= (Tr(M), Tr* (m)) is linear. (c) Generalize the prior item.
