No I just have to come up with a vector in R^5 that does not lie in span (a1, a2, a3). Try the row reduction again. Also express in this basis the vector. I have expanded a1, a2, and a3 to a basis for R^5 by adding e1 = (1,0,0,0,0) and e2 = (0,1,0,0,0).

WebSpan: implicit definition Let S be a subset of a vector space V. Definition. The span of the set S, denoted Span(S), is the smallest subspace of V that contains S. That is, • Span(S) is a subspace of V; • for any subspace W ⊂ V one has S ⊂ W =⇒ Span(S) ⊂ W. Remark. The span of any set S ⊂ V is well WebApr 11, 2024 · In particular, A1 refers to the concept of ratio, whereas A2 and A3 are related to the understanding of proportional relationships (both direct and inverse). On the other hand, A4 accounts for understanding of nonproportional relationships such as additive and affine relationships and distinguishing directly and inversely proportional ...
