    1. Determine the vector \overrightarrow{AB}=(8,2). And now calculate the length of \overrightarrow{AB}.

    2. As I've noticed in your previous post you know how to get a unit vector. Go on!

    3. Keep in mind that the positive x-axis points in the same direction as the vecor \vec a = (1,0)

    ok i think i got it right up to question 3. I think i'm getting confused about which angle to work out.

    I think i just needed to plot the AB vector and find the angle between the vector line and x-axis
