$vorv $

Graphically, a vector is usually represented by an arrow where the length of the arrow represents the magnitude and the arrowhead represents its direction.
Vectors are drawn between two points, the initial point and the terminal point. For example, if a vector is drawn between $A$ and $B,$ it can be named $AB$ or $BA$ depending on the initial point and terminal point. The part of the vector that lies on the initial point is called the

A vector can also be written in component form. In two dimensions, this is $⟨x,y⟩.$ Here, the first coordinate is the horizontal change and the second coordinate is the vertical change.

In the case of a vector in a three-dimensional space, the component form is $⟨x,y,z⟩.$ Here, the coordinates represent the change in the direction of their corresponding axes.
