alleryCosines of the angles a vector makes with the axes are its:
AVector components
BDirection cosines
CDirection ratios
DScalar components
Answer & Solution
Correct answer: B. Direction cosines
1. The angles made with the positive x, y and z axes are direction angles.
2. The cosines of those angles are the direction cosines.
3. They are usually written as l, m and n.
