Chapter 3. Vector Spaces and Subspaces
Suppose V₁, V2, V3, V4 are vectors in R³.
(a) These four vectors are dependent because
(b) The two vectors v₁ and v2 will be dependent if
(c) The vectors v₁ and (0, 0, 0) are dependent because
10 Find two independent vectors on the plane x+2y-3z-t = 0 in R4. Then find three
independent vectors. Why not four? This plane is the nullspace of what matrix?
Questions 11-14 are about the space spanned by a set of vectors. Take all linear com-
binations of the vectors.
11 Describe the subspace of R³ (is it a line or plane or R³?) spanned by
(a) the two vectors (1, 1, -1) and (-1,-1,1)
(b) the three vectors (0, 1, 1) and (1, 1, 0) and (0, 0, 0)
(c) all vectors in R³ with whole number components
(d) all vectors with positive components.
