Pursuit Curve
If 
moves along a known curve, then 
describes a pursuit curve if is always directed toward and and move with uniform velocities. These were considered in general by the French scientist Pierre Bouguer in1732. The case restricting to a straight line was studied by Arthur Bernhart (MacTutor Archive). It hasCartesian Coordinates equation
