This illustrates one of the most fundamental ideas in linear algebra. The plane going through .0;0;0/ is a subspace of the full vector space R3. DEFINITION A subspace of a vector space is a set of vectors (including 0) that satisfies two requirements: If v and w are vectors in the subspace and c is any scalar, then
We know C(A) and N(A) pretty well. Now the othertwo subspaces come forward. to thousands of linear algebra students. Those subspaces are the column space and the nullspace of Aand AT. They lift the understandingof Ax Db to a higherlevelŠasubspace level. The rst step sees Ax (matrix times vector) as a combination of the columns of A. Those vectors Ax ll the column space C.A/.

Consider the following useful Corollary. Theorem \(\PageIndex{2}\): Span is a Subspace. Let \(V\) be a vector space with \(W \subseteq V\). The concept of a subspace is prevalent throughout abstract algebra; for instance, many of the common examples of a vector space are constructed as subspaces of R n \mathbb{R}^n R n. Subspaces are also useful in analyzing properties of linear transformations, as in the study of fundamental subspaces and the fundamental theorem of linear algebra. 2007-12-08 This Linear Algebra Toolkit is composed of the modules listed below. Each module is designed to help a linear algebra student learn and practice a basic linear algebra procedure, such as Gauss-Jordan reduction, calculating the determinant, or checking for linear independence.

2. SUBSPACES AND LINEAR INDEPENDENCE 2 So Tis not a subspace of C(R). By the way, here is a simple necessary condition for a subset Sof a vector space V to be a subspace. Proposition 2.6. If Sis a subspace of a vector space V , then 0 V 2S. Proof. A subspace Swill be closed under scalar multiplication by elements of the underlying eld F, in
If Sis a subspace of a vector space V , then 0 V 2S. Proof.

Linear equations give some of the simplest descriptions, and systems of linear equations are made by combining several descriptions. In this unit we write systems of linear equations in the matrix form Ax = b.
