Does a span always include the zero vector

WebSep 17, 2024 · Keep in mind, however, that the actual definition for linear independence, Definition 2.5.1, is above. Theorem 2.5.1. A set of vectors {v1, v2, …, vk} is linearly dependent if and only if one of the vectors is in the span of the other ones. Any such vector may be removed without affecting the span. Proof. WebUsing the linear-combinations interpretation of matrix-vector multiplication, a vector x in Span {v1, . . . , vn} can be written Ax. Thus testing if b is in Span {v1, . . . , vn} is equivalent to testing if the matrix equation Ax = b has a solution.
