**Graphical Representation.**

Graphically a vector is represented by an arrowhead line segment.The length of the line gives the magnitude of vector on a certain scale and arrow indicates the direction of the vector.

**Head to Tail Rule.**

Head to tail rule is the graphical method of vector addition. According to this method

“Two or more vectors can be added by drawing the vector lines in such a way that the head of one vector coincide with the tail of the other. The vector line obtained by joining the tail of first vector to the head of the last vector represent the resultant vector which is directed from the tail of first vector to the head of last vector”.
