Simply take B from A i = 10-3=7 j= -3-2=-5 k= 2-5=-3 SO the velocity is (7i-5j-3k)

dy/dx= 6x + 30x^4 - 2/x^2

Ok I see why you are asking yourself this since right now you are only expressing certain formulae in a different way. Let me first talk about something else before giving you this answer. When you were i...
