@5:30 why are both sums running over K? Shouldn't the first sum run over index i? +LadislauFernandes

You have to use more than two matrixs to prove that trace is invariant under cyclic permutations lol, it will always work for A and B.

Can you help me! Proof: if A<=B then Tr(A)<=Tr(B), where <= i.e. greater than or equal. Thank you very much!
