Let F be a field and V a vector space over F with the basis {v1, v2, ..., vn}. (a) Consider the set S = {T : V -> F | T is a linear transformation}. Define the operations: (T1 + T2)(v) := T1(v) + T2(v), (aT1)(v) = a(T1(v)) for any v in V, a in F. Prove tat S with these operations is a vector space over F. (b) In S, we have elements fi : V -> F...

operator T : V → Fn in the following way: For each x =

operator.

P4. Prove: If V = {V1, V2, ...,V) is a linearly indepen- dent set of vectors in R", and if W = {Wx+1, ...,wn} is a basis for the null space of the matrix A that has the vectors V1, V2, ..., Vk as its successive rows, then VUW = {V1, V2, ..., Vk, Wk+1,...,w.} is a basis for R". [Hint: Since V UW contains n vectors, it suffices to show that VUW is linearly independent. As a first step,...
explain what a basis for a vector space is. How does a basis differ from a span of a vector space? What are some characteristics of a basis? Does a vector space have more than one basis? Be sure to do this: A basis B is a subset of the vector space V. The vectors in B are linearly independent and span V.(Most of you got this.) A spanning set S is a subset of V such that all vectors...
