If l,m,n are direction cosines of a line , then vector `li +mj+nk` is a

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

If l, m, n are direction cosines of a line then l hat(i) + m hat(j) + n hat(k) is________

If l, m, n are direction cosines of a line, then the maximum value of lm+mn+nl is

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

If (l,m,n) are direction cosines of a line then L^(2)+m^(2)+n^(2)

l=m=n=1 represent direction cosines of
