[数学][几何] 数学之心函数曲线动图

实干、实践、积累、思考，创新。

---

网上看到的数学之心曲线，函数是：

f(x)=x^2/3 + 0.9*(3.3-x*x)^1/2*sin(b*π*x)

主要参数为 x,b，其中参数x2<3.3，在整个x范围内，改变b可观察到心的形状。

可以通过EXCEL绘制几组b 值下f(x)的函数曲线。

b=1

b=3

b=5

b=8

b=10

b=20

b=40

b=60

可以发现b越大，越接近心形。

最后我们可以把曲线导入之前的编写的 GAAGM软件 [软件][工具][编程] GAAGM: Graph Animation and Animated Gif Maker [曲线图动画及Gif动图生成工具]，制作漂亮的曲线动画。
