Direction cosine of line joining two given points
In three-dimensional geometry, lines that intersect the x, y, and z axes are referred to as the direction cosines of the line. They are defined as follows: To preserve consistency, the letters l, m, and n are often employed to denote these directional cosines. Cosine angles may be determined only after the angle formed […]
