Which of the following must be true?
OThe set of all n x matrices having trace equal to zero is a subspace of Mnxn (R)
OLet V = {(x, y) : x, yeR}For any (x1, Y1), (x2, Y2)eV and c eR, we have (æ1, Y1) + (x2, Y2} (x1 + x2, Y1 – Y2)
and c (x1, y1) = (cx1, cx2)Then V is a 2-dimensional vector space over R.
For any two (3x3) matrices A and B, we must have (A+ B)? = A² + 2AB + B?
Olf M is a linearly dependent set, then every vector in M is a linear combination of other vectors in M.
