The direction cosines of a line are the cosines of the angles that the line makes with the coordinate axes. For lines L1 and L2, we have: - For line L1: (l1,m1,n1) - For line L2: (l2,m2,n2) 2. Dot Product Formula: The cosine of the angle θ between two vectors (or lines)...

What this means is that direction cosines do not define how much an object is rotated around the axis of the vector. Further Reading For applications of unit length vectors to specify directionsee here. You may be interested in means to represent orientation and rotational quantities such as: ...
Direction cosines of the vector are the cosines of the angles between the vector and the three coordinate axes. The direction cosines are given by l, m, n. The angles made by vectors with x, y and z axes are α,β,γ respectively. Therefore, the direction cosine of the vector with th...
