Question

I need help finding the unit vector that has the same direction as the vector v = –12j.

Answer 1

We put a little cap on the v to signify that it's the unit vector.
Since the vector only has one component it's easier to find the unit vector.

It's in the same direction, but with a length of 1.
So it will still be going negative, in the j direction, but with a length of 1.
