I know it's been a while, but does anyone else think it's worth complaining about the wording in the last vector question ("foot of the perpendicular" ["gwaelod y perpendiciwlar" for those who did it in Welsh])? Had they just said "the point of intersection of AB and L" then I, as I think many of us, would have known exactly what had to be done - it was the terminology that threw me. What do people think?
