Web17 sep. 2024 · Theorem 9.4.2: Spanning Set. Let W ⊆ V for a vector space V and suppose W = span{→v1, →v2, ⋯, →vn}. Let U ⊆ V be a subspace such that →v1, →v2, ⋯, →vn ∈ U. Then it follows that W ⊆ U. In other words, this theorem claims that any subspace that contains a set of vectors must also contain the span of these vectors.
