Note that the ...My advice in this kind of situations is to show that the space U is closed under addition and under multiplication by scalar. $\endgroup$ – Niki Di Giano Mar 3, 2018 at 20:122 Answers. A subspace must be closed under scalar products. And, a subspace must be a non-empty subset. So, if you have a subspace, then you have at least one vector v in it. Then, you also have the scalar product 0 ⋅ v in the subspace. But, it follows from the distributivity axioms in a vector space, 0 ⋅ v = 0 always.Then the set V V, of position vectors of points of Π Π, is given by V = {μa +νb: μ,ν ∈ R} V = { μ a + ν b: μ, ν ∈ R }.

Example 1. The set W of vectors of the form (x,0) ( x, 0) where x ∈ R x ∈ R is a subspace of R2 R 2 because: W is a subset of R2 R 2 whose vectors are of the form (x,y) ( x, y) where x ∈ R x ∈ R and y ∈ R y ∈ R. The zero vector (0,0) ( 0, 0) is in W. Then $$ \langle \alpha x+\beta y,a\rangle =\alpha \langle x,a\rangle +\beta \langle y,a\rangle =0 .$$ Therefore $ \alpha x+\beta y\in A^{\perp} $ and hence $ A^{\perp} $ is a liner subspace.

If you are unfamiliar (i.e. it hasn't been covered yet) with the concept of a subspace then you should show all the axioms. Since a subspace is a vector space in its own right, you only need to prove that this set constitutes a subspace of $\mathbb{R}^2$ - it contains 0, closed under addition, and closed under scalar multiplication. $\endgroup$
