WebBut statement (2) doesn't tell us anything new -- it follows directly from statement (1). In fact, it's called the "contrapositive" of statement #1. Similarly, (4) doesn't tell us anything new, because it's just the contrapositive of (3). That's the logic. Intuitively, a set of vectors needs to be "big" and "fat" in order to span a space. WebThere is a single zero row, so (i) we have linear dependence and (ii) the dimension is 3, so your basis will have 3 elements. You can check, using your row reduction, whether taking the first three vectors will do the job. – André Nicolas Apr 2, 2012 at 22:07 Add a comment 2 Answers Sorted by: 2

WebOne maximal linearly independent subset consists of the pivot columns of A—i.e., B = ... span(S) in terms of a minimal spanning set. Solution: No, S does not span R4 since rref(A) does not have a pivot in every row. A minimal spanning subset of S is the set B found in part (a), and span(S) = span(B). ... Find a basis for the span of the four ... WebHence any set of linearly independent vectors of R 3 must contain at most 3 vectors. Here we have 4 vectors than they are necessarily linearly dependent. To find out which of these 4 vectors are linearly independent we proceed by row reducing the matrix whose columns are the 4 given vectors.

WebThe subspace defined by those two vectors is the span of those vectors and the zero vector is contained within that subspace as we can set c1 and c2 to zero. In summary, the vectors that define the subspace are not the subspace. The span of those vectors is the subspace. ( 103 votes) Upvote. Flag.
