difference of vectors
Thus we have
According to the procedure of forming the sum of vectors by setting the addends one after the other, the equation (1) tallies with the picture below; when the minuend and the subtrahend emanate from a common initial point, their difference vector can be directed from the terminal point of the subtrahend to the terminal point of the minuend.
Remark. It is easily seen that the difference is same as the sum vector
where is the opposite vector of : it may be represented by the directed line segment from the terminal point of to the initial point of .
