Ok I have a question.. can someone please explain to me what it is asking me to do, and maybe show me working for this example?
Find a unit vector in the direction of the following vector:
i + j
Thanks.

Just divide the vector by its modulus. In this case,

Its modulus?

modulus of a vector = magnitude of a vector = 'its length' in cartesian coordinates, use pythagoras

If you take a vector of length L and you divide it by L, what size would you expect the resulting vector to be?
"In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..."

How did you know do that form the question though? :S
Edit: And why do you do that division?

Forget it... I understand now. Thanks. I didn't realise it wanted a magnitude of 1.
