of vectors. If you have three dependent vectors (v₁, v₂, v₃) then Span(v₁,v₂,v₃)=Span(v₁,v₂) or possibly even just Span(v₁). On the other hand, if you have three independent vectors, Span(v₁,v₂,v₃)=ℝ³, and if you have n independent vectors, then Span(v₁…vₙ)=ℝⁿ. If vectors are dependent, the span is
