vectorsdirectional
Vectorsdirectional refers to the concept of directional vectors in vector mathematics and its applications. A directional vector is a nonzero vector that indicates the orientation of a line, ray, or curve in space. It can be obtained as the difference between two points on the object, such as v = q − p for a line through points p and q, or as the direction parameter in a parametric equation. Any nonzero scalar multiple of a direction vector represents the same direction; the unit direction vector is v̂ = v / ||v||, providing direction with unit length.
Directional vectors are used to define lines and rays, specify the orientation of physical quantities like
Important properties include independence from magnitude and dependence on direction. The same direction can be represented
