  Bases and         Yesterday, we saw how to construct a subspace of a vector
  Dimension
                    space as the span of a collection of vectors.
                    Question
                    What’s the span of v1 = (1,1) and v2 = (2,−1) in R2?
                    Answer: R2.
                    Today we ask, when is this subspace equal to the whole vector
                    space?

  independence      Definition
  Bases and         Let V be a vector space and v ,...,v ∈ V. The set
  Dimension                                                         1           n
                    {v1,...,vn} is a spanning set for V if
                                                    span{v1,...,vn} = V.
                      Wealso say that V is generated or spanned by v1,...,vn.
                    Theorem
                    Let v1,...,vn be vectors in Rn. Then {v1,...,vn} spans Rn
                                                                                                    
                    if and only if, for the matrix A = v1                         v2 ···         vn , the
                    linear system Ax = v is consistent for every v ∈ Rn.
