So that means that they are not a basis for the column space of A. They do span the column space of A, by definition really. But they're not a basis. They need to be linearly independent for them to be a basis. So let's see if we can figure out what a basis for this column space ... Well, 2. And that tells us that the basis for a plane has 2 vectors in it. If the dimension is again, the number of elements/vectors in the basis, then the dimension of a plane is 2. So even though the subspace of ℝ³ has dimension 2, the vectors that create that subspace still have 3 entries, in other words, they still live in ℝ³.An important result in linear algebra is the following: Every basis for V V has the same number of vectors.

Example A.4. 1. If we let S = Rn, then this S is a subspace of Rn. Adding any two vectors in Rn gets a vector in Rn, and so does multiplying by scalars. The set S ′ = {→0}, that is, the set of the zero vector by itself, is also a subspace of Rn.We can view $\mathbb{C}^2$ as a vector space over $\mathbb{Q}$. (You can work through the definition of a vector space to prove this is true.) As a $\mathbb{Q}$-vector space, $\mathbb{C}^2$ is infinite-dimensional, and you can't write down any nice basis. (The existence of the $\mathbb{Q}$-basis depends on the axiom of choice.)Since \(V\) has a basis with two vectors, its dimension is \(2\text{:}\) it is a plane.

This would be a graph of what our column space for A could look like. It is a 2D plane, dictated by our two 2D basis, independent vectors, placed in a R³ environment. The image is the set of all points in $\mathbb{R}^4$ that you get by multiplying this matrix to points in $\mathbb{R}^5$, you can find these by checking the matrix on the standard basis. The kernel is the set of all points in $\mathbb{R}^5$ such that, multiplying this matrix with them gives the zero vector. Again you can find this in a similar way.The dimension of a vector space is defined as the number of elements (i.e: vectors) in any basis (the smallest set of all vectors whose linear combinations cover the entire vector space).
