Vocabulary A-Z

Let us learn some vocabulary
standard position
A vector in standard position has its initial point at
vector the origin.
A vector is a quantity that has both magnitude, or
length, and direction, and is represented by a
directed segment. In the diagram, CD is in standard position and
can be represented by the ordered pair
y <4, 2>.
