Find the direction cosines of the line

Given : A line

To find : Direction cosines of the line

Formula used : If a line is given by = = then direction cosines are given by , ,

The line is = =

Here l = -2 , m = 6 , n = -3

Direction cosines of the line = = is

, ,

= , , = , ,

= , ,

Direction cosines of the line = = is , ,
