3 4 linear dependence and span p. Oct 2019 1 0 hong kong. If however our set of vectors do not span all of then we say they are linearly dependent this is will happen if our vectors are lying on the same line or same plane in 3d and so one will just be a scaled version of the other. We know that the matrix s rank and therefore linear dependence and the span in linear algebra are determined by the number of non zero rows.

This means that in our case we have rank a 2 which is less than the number of vectors and implies that they are linearly dependent and span a 2 dimensional space. I want to bring everything we ve learned about linear independence and dependence and the span of a set of vectors together in one particularly hairy problem because if you understand what this problem is all about i think you understand what we re doing which is key to your understanding of linear algebra these two concepts. Hence when we come to write a linear combination at least one of the vectors will be redundant since the idea is to scale vectors and then add them to each other to.
