SirLancelotDuLac
We are not adding the x, y and z components, we are only concerned with 2 x components, 2 y components...etc

oooh i get it nw mb
SirLancelotDuLac
Ah I see. Its just that you have taken the order of selection into account and hence, are getting an additional factor of 2.

I am sorry but I don't get it...can you explain it again pls
SirLancelotDuLac
I mean let the points be (a,b,c) and (d,e,f). Ig the case (a,b,c),(d,e,f) amd (d,e,f)(a,b,c) are counted separately which should not be the case
