Question

Could you please just give me a simple explanation on part (b) with its subparts (a) & (b). Thank you

(1) Let V be a vector space over any field F:
(a)
Prove that V is infinite dimensional iff there is a sequence of vectors (V₁, V2, V3, ... )
in V such that V₁, V2, ..., Um is Linearly independent for each positive integer m.
(b) Use the above to conclude the following two vector spaces are infinite dimensional
C-vector spaces:
(a)
(b)
V = Fct(Z, C)
V = C[t] (the vector space of all polynomials)
