  Calculate position vector and derivative unit vector

+ 0 like - 0 dislike
31 views

What is the difference between calculating the unit vector + derivative separate like positionVector/normPosVector and derivativeVector/normDerVect example position and velocity and calculating the derivative norm vector as d(positionVector/ normPosVector) when we use one or the other method? Thanks a lot! John
