another constant quantity a collinear two opposite projection vectors C and C ' . Request B on a projection vector C, we can use a number multiplied by a unit vector, this unit vector and a direction one to, we remember as A1. And this number is the projection length of b on a .First, to find the unit vector A1, we know that it is vector a multiplied by its own length of the reciprocal (number multiplication vector), its length weYou can find that M
