Webfor all u;v2V and all 2F. A vector space endowed with a norm is called a normed vector space, or simply a normed space. An important fact about norms is that they induce metrics, giving a notion of convergence in vector spaces. Proposition 1. If a vector space V is equipped with a norm kk: V !R, then d(u;v) , ku vk is a metric on V. Proof. http://web.mit.edu/r/current/lib/R/library/base/html/norm.html

"WebUnit Vectors. A vector of a norm of 1 is a unit vector. Unit vectors are of use when length is not relevant. The unit vector $\textbf{u}$ is defined as: \[\displaystyle \textbf{u} = \dfrac{1}{ \textbf{v} } \cdot \textbf{v}\] where v is a non-zero vector in $\mathbb{R}^{n}$. When we obtain a unit vector u from v, it is called normalizing v. " - Norm of vector in r
