#469 Re: Help Me ! » Vector 2 » 2016-10-29 16:20:57

I read all topic of vectors but not understand what is this in this link

#470 Re: Help Me ! » Vector 2 » 2016-10-29 15:37:19

the cross product, a × b, returns a vector that is perpendicular to both a and b
How perpendicular what is methods of a.b and a×b etc plz tell
