Question

What are coinitial and collinear vectors

Answer 1

◆ co initial vectors

The vectors which have the same starting point are called co-initial vectors. The vectors \overrightarrow{AB} and \overrightarrow{AC} are called co-initial vectors as they have the same starting point.

◆collinear vectors

Definition 2 Two vectors are collinear, if they lie on the same line or parallel lines. In the figure above all vectors but f are collinear to each other. Definition 3 Two collinear vectors are called co-directed if they have the same direction.
