WebExpert Answer. Directions: Determine if the set of vectors S is a spanning set for V. If it is a spanning set, write an arbitrary vector in V as a linear combination of the vectors in S. If it is not a spanning set, then find the subspace that it does span by using a set of equations to describe it. 1. S = {[ 2 5],[ 4 11]},V = R2. WebSince the plane must contain the origin—it's a subspace— d must be 0. This is the plane in Example 7. Example 3: The subspace of R 2 spanned by the vectors i = (1, 0) and j = (0, 1) is all of R 2, because every vector in R 2 can be written as a linear combination of i and j: Let v 1, v 2 ,…, v r−1 , v r be vectors in R n .
