Question

How do you describe a vector using vector notation. Basically what is vector notation?

Answer 1

Vector notation is a language to describe the real world just few symbol which describe a vector quantity.
Vector notation has many kinds which you can use to complete describe a vector.
these types are there http://en.wikipedia.org/wiki/Vector_notation

Answer 2

There are many vector notations. Before trying to pin down the one you are asking about, what two things do you need to know about a vector?

Answer 3

Describe this vector using vector notation.

Answer 4

By which type ??

Answer 5

My guess is that the question is meant in a straightforward way: "What is the x- and the y-component of this vector?"

Answer 6

Judging from the scan of the paper, they are probably doing only the basics, so IMHO they are required to give the ordered set notation of the rectangular vector in R^2, which goes like this:\[v = (xcomponent, ycomponent)\]There should be an arrow above the v to denote a vector but I'm unsure how to do it here :-)

Answer 7

So @laura_0008 you look at the paper, find out how long the x-component is (say, its length is 7 squares of the grid) and then you find out the same about the y-component (let's say its length is 4 squares of the grid, as in my sketch). You'd then write the vector v as:\[v = (7,4)\]Mind you, there should be an arrow above the v to denote it is a vector. x-values to the right of the intersection of axes are positive, to the left they are negative. y-values upwards are positive, y-values downwards are negative. So this for example would be v = (-2,-5)
