In any -dimensional vector space, any set of linear-independent vectors forms a basis. (0,0,1), (0,1,0), and (1,0,0) do span R3 because they are linearly independent (which we know because the determinant of the corresponding matrix is not 0) and there are three of them. The simplest example of such a computation is finding a spanning set: a column space is by definition the span of the columns of a matrix, and we showed above how . Whats the grammar of "For those whose stories they are". This comes from the fact that columns remain linearly dependent (or independent), after any row operations.
