Representing vectors

You can represent vectors in 3 ways:

$a$	or	$vec (AB)$	or	$((3),(4))$
Lower case letter		Capitals with an arrow above		Column

As follows

The values of a vector can be represented in 3 different ways

Further examples

Example 1

There are three vectors making this triangle A,B and C

This triangle is made up of three vectors:

$a$ , $b$ and $c$

Example 2

This triangle also contains three vectors but is represented differently to the one above

This triangle is made up of three vectors:

$vec (AB)$ , $vec (BC)$ and $vec (CA)$

Example 3

This triangle is also represented differently but showing values in columns

This triangle is made up of three vectors:

$((2),(3))$ and $((2),(-3))$ and $((-3),(0))$
