A unit vector is a vector that has a magnitude of exactly one. Unit vectors are typically used to indicate direction without regard to magnitude. In mathematical terms, a unit vector is often denoted with a "hat" symbol, such as \\(\\hat\{u\}\\). For any vector \\(\\mathbf\{v\}\\), the unit vector in the direction of \\(\\mathbf\{v\}\\) can be computed by dividing the vector by its magnitude (or length).
