If you want to know why the intersection of subspaces is itself a subspace, you need to get your hands dirty with the actual vector space axioms. Subspaces - Examples with Solutions Definiton of Subspaces. If W is a subset of a vector space V and if W is itself a vector space under the inherited operations of addition and scalar multiplication from V, then W is called a subspace.1, 2 To show that the W is a subspace of V, it is enough to show that .

Then \(U\) is a subspace of \(V\) if and only if the following three conditions hold. additive identity: \( 0 \in U \);cancellation we just proved gives us u = w, so inverses are unique.Even more readily, if 0 and 0N both will serve as the identity, then 0 = 0 + 0N = 0N.Thus a vector space has only one identity. From this it follows that, since, v = (1 + 0)v = 1v + 0v = v + 0v implies that 0v is an identity, 0v = 0.Finally, 0v = (1 + -1)v = 1v + (-1)v = v + (-1)v and so, by the …Prove that a subset W of a vector space V is a subspace of V if and only if 0 ∈ W and ax+ y ∈ W whenever a ∈ F and x, y ∈ W.

If V is a vector space over a field K and if W is a subset of V, then W is a linear subspace of V if under the operations of V, W is a vector space over K.Equivalently, a nonempty subset W is a linear subspace of V if, whenever w 1, w 2 are elements of W and α, β are elements of K, it follows that αw 1 + βw 2 is in W. Let V and W be vector spaces, and let T: V W be a linear transformation. Given a subspace U of V, let T(U) denote the set of all images of the form T(x), where x is in U. Show that T(U) is a subspace of W. To show that T(U) is a subspace of W, first show that the zero vector of wis n TU. Choose the correct answer below. d A. ? B. O C. To prove that the intersection U ∩ V U ∩ V is a subspace of Rn R n, w...
