If (a,b,c) are direction ratios of a line then the direction cosines of the line (l,m,n)=

If the direction ratio of a line is 1,-2,2 Then what are the direction cosines of the line

If the direction ratios of a line are (-18,12,-4), then direction cosines of a line are

If a line has the direction ratios -1, 2, 3, then its direction cosines are

l = m = n = 1 are the direction Cosines of

If 1/2,1/3,n are direction cosines of a line, then the value of n is

If a line has direction ratios 2,1,2 determine its direction cosines.

If a line has the direction ratios 4, -12, 18, then its direction cosines are

If l , m, n are the direction consines of a line, then

If l_(1),m_(1),n_(2);l_(2),m_(2),n_(2), be the direction cosines of two concurrent lines,then direction cosines of the line bisecting the angles between them are proportional to
