Что (кто) такое direction cosine - определение


Direction cosine         
  • Direction cosines and direction angles for the unit vector '''v'''/{{pipe}}'''v'''{{pipe}}
  • Vector '''v''' in '''R'''<sup>3</sup>
COSINES OF THE ANGLES BETWEEN THE VECTOR AND THE THREE COORDINATE AXES.
Direction cosines; Directional cosine
In analytic geometry, the direction cosines (or directional cosines) of a vector are the cosines of the angles between the vector and the three positive coordinate axes. Equivalently, they are the contributions of each component of the basis to a unit vector in that direction.
