ok... back in school after a 3-week faculty strike.(adsbygoogle = window.adsbygoogle || []).push({});

I'm pretty sure I got this wrong:

specifics aren't important. the question was to find a point on a given plane closest to a point A.

What I did was find a point B on the plane, and do proj(n)(AB)

n being a normal to the plane.

... when I look in my textbook the answer to a question like this is perp(n)(BA). Are they both right, or did I do it wrong? ... I mean, it makes sense to me that a projection of AB onto n would land in the same place, no?
