Webvector space. Problem 4. Prove that the plane with equation x+y+z = 1 is not a vector space. (Do not use the Fact below.) Fact. Every vector space contains the origin. Proof: Let V be a vector space. Since a vector space is nonempty we can pick a v ∈ V. Then 0v = 0, so the origin, 0, is in V. Problem 5. Weba vector space over R with componentwise addition and scalar multiplication. 2. ... then this is precisely property 1 in the definition of vector space. Also since S is not empty there is some v in S. Closure under scalar multiplication then implies that 0v = 0 is in S. Thus, S includes the identity as required by property 4.
