WebTo establish that A is a subspace of R2, it must be shown that A is closed under addition and scalar multiplication. If a counterexample to even one of these properties can be found, then the set is not a subspace. In the present case, it is very easy to find such a counterexample. Webaddition and scalar multiplication. Note that V is not closed under addition: for a;b;c;d 2R, we have 1 a b 1 and 1 c d 1 but 1 a b 1 + 1 c d 1 = 2 a+ c b+ d 2 2= V: We conclude that …

WebMar 24, 2024 · A vector space is a set that is closed under finite vector addition and scalar multiplication. The basic example is -dimensional Euclidean space, where every element … WebMar 4, 2014 · An element is closed under addition iff an element, u A, and, v A such that u^2+v^2 = <=1. If u^2+v^2 <=1, then, u and v is a subset of A. You have a very confused interpretation. You don't talk about whether an element is closed under addition, you talk about whether the subset is closed under addition. That is, if and are in , is always in ?
Webclosed under both addition and scalar multiplication. We give such subsets a name: Definition 8.3.2: Subspace of Rn A subset S of R nis called a subspaceof R if for every scalar c and any vectors u and v in S, cu and u+ v are also in S. That is, S is closed under scalar multiplication and addition.
