... then their union is also independent. • The claim then follows from Zorn’s Lemma. • To show that such a maximal independent set must be a basis, we proceed by contradiction: • If this is not true, there is some vector v that is not in the span. • Adding this to the set gives us a larger independent ...

... Answ: Yes. Periodic functions form a vector space. (It may be impossible, though, to introduce a workable inner product). c) How about all functions with f (0) = 4? Answ: No. This vector space wouldnt behave properly under addition: (f +g)(x) = f (x) + g(x) wouldnt work for (4 + 4 6= 4). ...

Basis (linear algebra)
Basis vector redirects here. For basis vector in the context of crystals, see crystal structure. For a more general concept in physics, see frame of reference.A set of vectors in a vector space V is called a basis, or a set of basis vectors, if the vectors are linearly independent and every vector in the vector space is a linear combination of this set. In more general terms, a basis is a linearly independent spanning set.Given a basis of a vector space V, every element of V can be expressed uniquely as a linear combination of basis vectors, whose coefficients are referred to as vector coordinates or components. A vector space can have several distinct sets of basis vectors; however each such set has the same number of elements, with this number being the dimension of the vector space.
