右边，为了绘制教科书上常见的样式，第二部分做了如下改进：
<\enumerate>
<item>取消边框
<item>设置过原点的坐标轴
<item>设置横轴和纵轴的刻度
<item>设置横轴和纵轴的箭头
<item>设置横轴和纵轴的范围
</enumerate>
大家只需要复制代码片段，更改第一部分的预设的值和函数，更改最后一部分的plot绘制命令即可。

右边，当我们将椭圆方程 <math|<frac|x<rsup|2>|4>+<frac|y<rsup|2>|9>=1> 视为函数 <math|f<around*|(|x,y|)>=<frac|x<rsup|2>|4>+<frac|y<rsup|2>|9>-1> 时，这个函数在 <math|f<around*|(|x,y|)>=0> 时描述的就是椭圆的边界。通过绘制这个函数的等高线，并且只选择 <math|f<around*|(|x,y|)>=0> 这一特定的等高线，我们就可以得到椭圆的图形。
