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

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

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

If (1/3,1/4,k) are the direction cosines of a line then the value of k is

If l,m,n are direction cosines of the line then -l,-m,-n can be

If l,m,n are the direction cosines of a half line op then the maximum value of l.m.n is

Direction cosine of a line is 1/sqrt(2), 1/2, n then the value of n is :

If l,m,n are direction cosines of the line then -l,-m,-n can be: a) only direction ratios of the line b) only direction cosines of the line c) direction cosines and direction ratios of the line d) neither direction cosines nor direction ratios of the line

If l_(1), m_(1), n_(1) and l_(2), m_(2), n_(2) are the direction cosines of two lines and l , m, n are the direction cosines of a line perpendicular to the given two lines, then

If (1,2,1), (1,-3,2) are the direction ratios of two lines and (l, m,n) are the direction cosines of a line perpendicular to the given lines, then l + m + n

l=m=n=1 represent direction cosines of
