< Definition:Vector Length(Redirected from Definition:Vector Length in Arrow Representation)Jump to navigation Jump to search
Let $\mathbf v$ be a vector quantity represented as an arrow in a real vector space $\R^n$.
The length of $\mathbf v$ is the length of the line segment representing $\mathbf v$ in $\R^n$.
Also known as
The length of a vector is also referred to as its module in some older books.
