Is the the projection of AB onto a direction vector d the same as the pAB onto a direction vector d? What exactly determine the direction of the projection vector??
Thank you
projAB onto d vs projBA onto d

0$\vec{AB}=-\vec{BA}$. So, their corresponding projections on $\vec{d}$ are different. BTW, projection is scalar quantity – 2017-01-28

0Is it generally good practive to start at the bottom of the vector AB to obtain a projection that has a same sign scalar as our vector AB? http://imgur.com/cLhTHsb – 2017-01-28
