Hi

Explanation:

if a vector →ABAB→ makes an angle θθ with a given directed line l, in the anticlockwise direction, then the projection of →ABAB→ on l is a vector →pp→ with magnitude |→ABAB→| cosθcos⁡θ.

Also, the direction of →pp→ is the same (or opposite) to that of the line l, depending upon whether cosθcos⁡θ is positive or negative. The vector →pp→ is the projection vector and has magnitude |→pp→|. It is also called the projection of vector →ABAB→ on the directed line l.
