No, they're not. Components are scalars. Components are the scalars you
multiply by the basis vectors to compose a vector. The product of a
component and a basis vector is a vector, but a component is not a
vector.
V = Sum(i) [vi * ei]
where V is a vector, vi are the components, and ei are the basis
vectors.
Do you want a math website reference to verify that?
