When graphed, a vector must meet a set of characteristics, such as:
Every vector uses an arrow symbol as a graphic representation.
If the ends of the arrow remain in the same place and order, the symbol used to represent it does not change, regardless of whether it is straight or has a curvature.
Vector are usually chained together to indicate their sum, so the end arrow of the first vector is joined to the initial point of the next one. This way, the line of the two ends is maintained.
If a vector arrow closes on itself, it means that it does not produce algebraic operations.
