Vectors:

Vectors are basically a way of describing the movement form

a starting point to and ending point.

In this pic, a vector is being used to describe the movement from

point A to point B. You can see in this pic that a bold a (a) has been

used to describe the movement from A to B.

There are also 2 other ways you can describe this vector.

This pic demonstrates another way to describe the same vector

shown above^^

Vectors are basically a way of describing the movement form a

starting point to and ending point.

So in this pic, you can describe the movement as .The starting

point is A. So this means, from A go 3 to the right and 4 up.

However, if you were at point B and were going to point A, you would go down 4 and left 3. You

would write that as but just with a minus sign (-) in front of the numbers. So basically right=

positive number. Left = negative number. Up= positive number. Down= negative number.

One other way of describing this movement from point A to

point B is just simply . So basically a -> b.
