Span Definition Let v1.v2,....Un be the vectors in a vector space V.A vector uEV is said to be a linear combination of v1.v2.....vn if there exist scalars c1. C2,·,Cn such that u C1v1+c2v2+...+CnUn. The set of all linear combinations of v1,v2.....Un is said to the span of U1.U2,....Un written S(v1,v2,...,Un)or span (v1,v2,...Un) 4口+心左4生主9QGSpan Definition Let v1, v2, . . ., vn be the vectors in a vector space V . A vector u ∈ V is said to be a linear combination of v1, v2, . . ., vn if there exist scalars c1, c2, . . ., cn such that u = c1v1 + c2v2 + . . . + cnvn. The set of all linear combinations of v1, v2, . . ., vn is said to the span of v1, v2, . . ., vn written S (v1, v2, . . . , vn) or span (v1, v2, . . . , vn)
