Direction Cosines And Direction Ratios
We study the different phenomena happening around us by using a 3D coordinate system. It has become crucial to study the behaviour of line, area, and volume elements in the 3D Cartesian coordinate system. The direction ratio tells us the orientation of a line segment with respect to the coordinate axes. We can draw a […]
