基于Flash AS3的正弦型函数作图器设计与实现

Design and Implementation of Sine Function Mapping Based on Flash AS3

以Flash CS5为设计平台,ActionScript3.0为编程语言,设计制作了一个正弦型函数的作图器。由用户输入参数A、ω、φ的值,按作图按钮即可作出函数y=Asin(ωx+φ)其长度为一个周期上的图象,按清除按钮可清除图形,重新输入参数作图。

Taking Flash CS5 as design platform and AetionScript 3.0 as the programming language, we design a sine func- tion mapping. The user inputs the value of parameters A , ω、φ ,and presses the drawing button to make a function y=A sin （ωx＋φ） . which is the image of a cycle in the length . If we Press clear button, we can clear the graphics. And if we input parameter, we can draw again.
