In mathematics, a unit vector in a normed vector space is a vector (often a spatial vector) of length 1. A unit vector is often denoted by a lowercase letter with a circumflex, or "hat", as in ^ (pronounced "v-hat"). The normalized vector û of a non-zero vector u is the unit vector in the direction of u, i.e.,

Wersor osi. Wersorem osi nazywamy wektor długości (normie) 1 o kierunku i zwrocie zgodnym z pewną dodatnią półosią prostokątnego układu współrzędnych. Dla osi oznacza się je tradycyjnie na kilka sposobów: , {\displaystyle \varepsilon _ {1},\varepsilon _ {2},\varepsilon _ {3}.}
Ilustracja wektora. Wektor [a] – obiekt matematyczny opisywany za pomocą wielkości: modułu (nazywanego też – zdaniem niektórych niepoprawnie – długością [b] lub wartością [c]), kierunku wraz ze zwrotem (określającym orientację wzdłuż danego kierunku); istotny przede wszystkim w matematyce elementarnej, inżynierii i fizyce.
In mathematics, physics, and engineering, a Euclidean vector or simply a vector (sometimes called a geometric vector [1] or spatial vector [2]) is a geometric object that has magnitude (or length) and direction.
A unit vector is any vector that is one unit in length. Unit vectors are often notated the same way as normal vectors, but with a mark called a circumflex over the letter (e.g. is the unit vector of .) [1][2] To make a vector into a unit vector, one just needs to divide it by its length: . [3]
By definition, the standard basis is a sequence of orthogonal unit vectors. In other words, it is an ordered and orthonormal basis. However, an ordered orthonormal basis is not necessarily a standard basis.
19 cze 2023 · A unit vector is a vector with a magnitude of 1. Unit vectors are marked with a cap symbol, which looks like a little arrow pointing upward: ^. To calculate a unit vector, divide the vector by its magnitude | |. In other words, follow this formula: ^ = | |.
