Slide1

Arbitrary vector spaces are so …it is not so easy to do any meaningful computa-tion in them. But, as we have seen, if we have a basis for an arbitrary finite dimensional vector space V, then the coordinate mappingestablishes an isomorphism (one-to-one, onto linear transformation) between V and
