WebWe know that the direction cosine is the cosine of the angle subtended by the line with the three coordinate axes, such as x-axis, y-axis and z-axis respectively. If the angles subtended by these three axes are α, β, and γ, then the direction cosines are cos α, cos β, cos γ respectively. The direction cosines are also represented by l, m, and n.
