Restating what we just saw in this lingo, the span of most pairs of 2D vectors is all vectors in 2D space, but when they line up, their span is all vectors whose tip sit on a certain line.

http://math.stanford.edu/%7Ejmadnick/R1.pdf NettetPut another way, a span is an entire vector space while a basis is, in a sense, the smallest way of describing that space using some of its vectors. For example, ℝ 2 is a vector space that is the span of the vectors (1,0) and (0,1), which serve as a basis for ℝ 2, i.e. we say that ℝ 2 = span { (1,0), (0,1)}. e27 11w led warm white light bulbs
