Which of the following must be true?
Let V = {(x, y) : x, yeR}For any (x1, Y1) , (x2, Y2)eV and c eR, we have (x1, Y1) + (x2, Y2= (x1 + x2, Y1 – Y2ànd
c (x1, y1) = (cx1, cx2) Then V is a 2-dimensional vector space over R.
The set of all n × nmatrices having trace equal to zero is a subspace of Mnxn (R)
O If Mis a linearly dependent set, then every vector in Mis a linear combination of other vectors in M.
If Vị and V2 are two distinct subspaces of the vector space V, then so is Vi U V2
O For any two (3x3) matrices Aand B, we must have (A + B)² = A² + 2AB+B²
