Direction ratios

Direction ratio and Direction cosine || Plane : Cartisian form & Normal Form

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

Direction ratio of the line segment joining two points

Find the angle between the pair of lines with directions ratios: ,

Write the direction ratio’s of the vector veca=hati+hatj-2hatk and hence calculate its direction cosines.

Direction ratio's of vectors 3hati+2hatj+4hatk are :
