Direction Ratios and Direction Cosines

admin2 years ago5 months ago06 mins

In three-dimensional geometry, direction ratios are used to represent the direction of a straight line in space. A direction ratio is a scalar value that specifies the change in the coordinates of a point on the line with respect to a unit change in the distance along the line in a particular direction. These direction…
