irányvektoras
The term "irányvektoras" is a Hungarian word that translates directly to "direction vector." In mathematics and physics, a direction vector is a vector that indicates a direction in space. It is often used to specify the orientation of a line, a plane, or a ray. Unlike a position vector, which describes a point's location relative to an origin, a direction vector does not have a specific magnitude or starting point. Its sole purpose is to define a direction.
Direction vectors are commonly represented by arrows. Their magnitude can be normalized to a unit vector, meaning
The concept of a direction vector is fundamental to understanding transformations in geometry, such as rotations
