What is a subspace and what is not?

The de nition of a subspace is a subset Sof some Rn such that whenever u and v are vectors in S, so is u+ v for any two scalars (numbers) and . However, to identify and picture (geometrically) subspaces we use the following theorem: Theorem: A subset S of Rn is a subspace if and only if it is the span of a set of vectors, i.e.

4 Span and subspace - Auburn University

Subspace. A subset S of Rn is called a subspaceif the following hold: (a) 0∈ S, (b) x,y∈ S implies x+y∈ S, (c) x∈ S,α ∈ Rimplies αx∈ S. In other words, a subset S of Rn is a subspace if it satisfies the following: (a) S contains the origin 0, (b) S is closed under addition (meaning, if xand yare two vectors in S, then

Subspaces - Mathematics

The Subspace Test To test whether or not S is a subspace of some Vector Space Rn you must check two things: 1. if s 1 and s 2 are vectors in S, their sum must also be in S 2. if s is a vector in S and k is a scalar, ks must also be in S In other words, to test if a set is a subspace of a Vector Space, you only need to check if it closed under ...
