two questions that i can't ever remember covering
first of all finding a perpendicular vector
find a vector perpendicular to the vectors a=i+2j-2k and b=-2i+3j+5k
and secondly the equation of a plane?? through point with position vector (2,1,1) and perpendicular to (3,-1,2) what are the forumla for finding these pieces of information?
