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 , ,
