Abstract:
A square chain of points is found that approximates a plane curve of the form F (x,y) =0. In case F (x,y) =0 represents a conic section, the method requires no multiplication or division, and so is well adapted to hardware or small computer software implementation. The algorithm may also be used to find approximate solutions of differential equations of the form F1dx + F2dy = 0.
