For a video explanation , click here 👉   https://youtu.be/8T7JZOyRO70   Theorem :       Let V ( F ) be a vector space and S = { 𝜶 1 , 𝜶 2 , … , 𝜶 n } is a finite subset of non – zero vectors of V ( F ). Then S is linearly dependent if and only if some vector 𝜶 k 𝟄 S , 2 ≤ k ≤ n , can be expressed as a linear combination of its preceeding vectors. Proof :  * linear sum of subspaces * What is a vector space * linear span of a set    * Theorem on vector space      * Historical Introduction to Linear Algebra   * Let V(F) be a vector space and let W ⊆ V. The necessary and sufficient conditions for W              to be a subspace of V are (i) 𝜶 𝞊 W, 𝞫 𝞊 W ⇒  𝜶 - 𝞫 𝞊 W                                                      (ii) a 𝞊 F , 𝜶 ?...
