Question: Can someone help me with vector projection?

I do not have any experience with maple and have a homework assignment due tomorrow. I have been staring at a screen blankly for an hour now trying to research how to do this but have had no luck. Here is my problem...

compute the projection of w onto v. call proj w onto v "p" and let q be vector perpendicular to p so that p+q=w. plot all four vectors together.

 

I have no idea where to even begin. I can do this by hand but it's the computer stuff and commands that are messing me up. THanks for any help.

v=<2,-1,3>

w=<1,-1,2>
