(English) : Vector
Definition Niveau 2
In elementary maths, a vector is a quantity which has both size and direction. For instance the wind might be measured by a vector, since it has both speed and direction.
Sometimes it is helpful to think of a vector as a directed line segment.
At a higher level we define a vector as a member of a set of objects which obeys the rules of vector algebra - i.e. a member of a vector space.
