Answer 3

a, b, c are three numbers proportional to the direction cosine l, m, n of a straight line, then a, b, c are called its direction ratios. They are also called direction numbers or direction components.

Hence by definition, we have

1/a = m/b = n/c = k

Answer 4

remember

• Direction cosines of a line are unique but direction ratios of a line in no way unique but can be infinite.
