After completing this tutorial, you will … fist bump lyrics youtubeIn mathematics, a norm is a function from a real or complex vector space to the non-negative real numbers that behaves in certain ways like the distance from the origin: it commutes with scaling, obeys a form of the triangle inequality, and is zero only at the origin. In particular, the Euclidean distance in a Euclidean space is defined by a norm on the associated Euclidean vector space, called the Euclidean norm, the 2-norm, or, sometimes, the magnitude of the vector. This norm c… fist bumps gif

"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
