Abstract: Iteration is a special graphic transformation similar to the recursive algorithm in programs, which can effectively solve some specific mathematical problems. At present, most dynamic geometry systems(DGS) have the iteration function, which meets the demand of teaching. NetPad, one of the DGSs, has optimized the iteration function on the basis of other sketchpads. This paper introduces the iteration function of NetPad. It provides the implicit iteration, random color hierarchy of each iteration object, trajectory iteration and iteration of iteration. Through teaching cases, the superiority of NetPad in iteration function is verified.
