The question is:
if vectors v1, v2, v3 belong to a vector space V does it follow that:
span (v1, v2, v3) = V
span (v1, v2, v3) is a subset of V.[/B]
2. The attempt at a solution:
If I understand it correctly the answer to both questions is yes.
The first: the linear combinations of these three vectors fill the space V.
Am I correct? I would like to make sure if I have understood the definitions.
