请问为什么输入abs(x)+abs(y)=1出现:"不正确的方程式:请输入关于 x.y的多项式方程参数不符合规则abs(x)",不能作图

Hi,


entering curves in implicit form is available for polynomial equations only.


To get the curve you want you may try something like

If[-1<=x<=1,1-abs(x)]

If[-1<=x<=1,-1+abs(x)]

谢谢,中文数学式子可以写成方程|x|+|y|=1并画出图形,其他语言不这样写吗?请问geogebea里没有设置这样的方程的画法吗?

现在可以输入隐函数了。就是某些功能还不太好。

输入 "x=(1-y^2)^(1/2)",曲线不能完整显示。
