V is as basis of Rn, so anything in V is also going to be in Rn. But V has k vectors. It has dimension k. And that k could be as high as n, but it might be something smaller. Maybe we have two vectors in R3, in which case v would be a plane in R3, but we can abstract that to further dimensions. distinguish bases ('bases' is the plural of 'basis') from other subsets of a set. Thus = fi;j;kgis the standard basis for R3. We'll want our bases to have an ordering to correspond to a coordinate system. So, for this basis of R3, i comes before j, and j comes before k. The plane R2 has a standard basis of two vectors,
