\begin{definition}[Definition:Linearly Independent/Set/Real Vector Space]
Let $\struct {\R^n, +, \cdot}_\R$ be a real vector space.
Let $S \subseteq \R^n$.
Then $S$ is a '''linearly independent set of real vectors''' if every finite sequence of distinct terms in $S$ is a linearly independent sequence.
That is, such that:
:$\ds \forall \set {\lambda_k: 1 \le k \le n} \subseteq \R: \sum_{k \mathop = 1}^n \lambda_k \mathbf v_k = \mathbf 0 \implies \lambda_1 = \lambda_2 = \cdots = \lambda_n = 0$
where $\mathbf v_1, \mathbf v_2, \ldots, \mathbf v_n$ are distinct elements of $S$.
