Let {V1, V2,...,Vn} be a linearly independent set of vectors choosen from vector space V. Define w1=V1, w2= v1+v2, w3=v1+ v2+v3,..., wn=v1+v2+v3+...+vn.
(a) Show that {w1, w2, w3...,wn} is a linearly independent set.
(b) Can you include that {w1,w2,...,wn} is a basis for V? Why or why not?

Problem 6.4 What does it mean to say that a set of vectors {v1, v2, . . . , vn} is linearly dependent? Given the following vectors show that {v1, v2, v3, v4} is linearly dependent. Is it possible to express v4 as a linear combination of the other vectors? If so, do this. If not, explain why not. What about the vector v3? Anthony, Martin.
