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))`
