e astute observer will have noticed that depending on the direction of the initial and
nal angles of the vehicles, the change in velocity vector may lie in one of the four quad-
rants of a standard Cartesian set of coordinates in the xy plane. e angle of the velocity
change, ΔA, is therefore dened as follows:
First quadrant: ΔA = a tan θ
Second quadrant: ΔA = 180 − a tan θ
ird quadrant: ΔA = 180 + a tan θ
Fourth quadrant: ΔA = 360 − a tan θ
where θ is the angle of ΔV with respect to the x-axis
