anonymous · Answer

Ooooh dang sorry I don't think I can do this one >.< Sorry dude

anonymous · Answer

No problem

anonymous · Answer

I can't even understand what the question asks, 

Unless it means that V is a Vector that is actually the normal vector n

anonymous · Answer

not to know i'm not given anything....

anonymous · Answer

Just how my professor is I suppose. He never provides constants. My assumption is that n is a separate orthogonal unit vector and v is a different 3D vector. Regardless, thanks for the interest at least.

anonymous · Answer

couldn't you say that:
$$c = v * n$$
(where * is the dot product)

anonymous · Answer

and that v perpendicular to the plane is c(n hat)

It's been a decade or so since I've done this stuff.. it looks like it just wants it all general according to definitions. Here's some stuff: http://www.euclideanspace.com/maths/geometry/elements/plane/lineOnPlane/index.htm
