| Abstract: | The Geometer's Sketchpad is easy to use, vivid, and has some dynamic effects. Based on the scenario of using rotating vector method to draw Lissajous Figures, this paper presents the detailed procedures of drawing Lissajous Figures with the Geometer's Sketchpad. A Lissajous Figure is presented by specifying certain parameters. |
