Definição de Subespaço Vetorial. | 03. Álgebra Linear.

Let V be a vector space. The non-empty subset W of V is called a vector subspace of V if it satisfies all three properties: (i) (Neutral element) 0 ∈ W (where 0 is the neutral element of the sum in V). (ii) (Closed with respect to the sum) if u, v ∈ W, then u + v ∈ W. (iii) (Closed with respect to the scalar product) if u ∈ W, then u ∈ αW, for every scalar α. --- Answer Key - Final Exercise. Redo the steps of Exercise 1) solved in the video lesson, but considering that an element u = (a, b) of W is such that 2a + b = 0. --- Help!
