Have a few vector questions I cant seem to get my head around.

    1. The problem statement, all variables and given/known data

    Ok, so here are the questions, I literally have no idea how to begin on them.

    1.Show that the vector 2i+3j+3k is normal to the plane containing the points (1,1,-2), (4,2,-5) and (1,-1,0). Hence find the equation of the plane in the form
    (r-a).n(hat)

    what is the perpendicular distance from the origin to the plane?


    There are a couple more questions but i'll take them one at a time.


    3. The attempt at a solution

    Been looking through my notes for ages and on th internet, cant find anything that makes sense, anyone good with vectors? thanks :)
    If anyone knows of a good vectors tutorial then i would be happy to see it.
