The sum of all the vectors is then found by drawing a vector from the tail of the first vector in the chain to the head of the last one (Fig. \PageIndex1(c)). The sum vector points from the tail...The sum of all the vectors is then found by drawing a vector from the tail of the first vector in the chain to the head of the last one (Fig. \PageIndex1(c)). The sum vector points from the tail of the first vector to the head of the last. (d) Vector subtraction: A−B points from the head of B to the head of A. (e) Multiplication of a vector A by various scalars.
