Homework Statement
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.
The Attempt at a Solution
Been looking through my notes for ages and on th internet, can't find anything that makes sense, anyone good with vectors? thanks :)
