Question 460760: Show that if s=(v1,v2,v3) is a linearly dependent set of vectors in a vector space V, and v4 is any vector in V that is not in S, then {v1,v2,v3,v4} is also linearly dependent
Answer by robertb(5830) (Show Source):
You can put this solution on YOUR website! Let S = { , , } be a linearly dependent set of vectors in V.
This means that there are scalars , , and , not all of them zero, such that . But then, we would also have , letting ; and not all of , , , and are equal to zero. Hence { , , , } is also a linearly dependent set.
