Norm of a Vector

Norm of a vector is the magnitude of that vector (length of the vector). The famous Pythagoras Theorem can be expanded to find out the norm of a vector in $\mathbb{R}^n$.
Norm of a vector is indicated with two vertical lines.
\begin{equation}
||\vec{v}|| = \sqrt{{v_1}^2+{v_2}^2+…+{v_n}^2}
\end{equation}
