Nettet16. sep. 2024 · This is a very important notion, and we give it its own name of linear independence. A set of non-zero vectors {→u1, ⋯, →uk} in Rn is said to be linearly independent if whenever k ∑ i = 1ai→ui = →0 it follows that each ai = 0. Note also that we require all vectors to be non-zero to form a linearly independent set.
