Plot a function of two variables equal 0
6
I would like to plot the function x2(1 − x2) − y2 = 0 in LaTeX.
I tried running following code
documentclass{article}
usepackage[margin=0.5in]{geometry}
usepackage[utf8]{inputenc}
usepackage{textcomp}
usepackage{pgfplots}
pgfplotsset{width=10cm}
begin{document}
begin{tikzpicture}
begin{axis}[
view={0}{90},
no markers,
]
addplot3+[
contour gnuplot={
levels=0,
labels=false,
}
]
{x^2(1-x^2)-y^2};
end{axis}
end{tikzpicture}
end{document}
but the output is
But should be
Thanks for helping.

@Superuser27 is correct about the missing *. Additionally, I don't understand why you're using addplot3. Finally, that's not a function.

usepackage[margin=0.5in]{geometry}
usepackage[utf8]{inputenc}
usepackage{textcomp}
usepackage{pgfplots}
pgfplotsset{width=10cm}

begin{tikzpicture}
begin{axis}[

addplot[domain=-1:1,samples=1000]{ sqrt(x*x*(1-x*x)) * -1 };
addplot[domain=-1:1,samples=1000]{ (x*x*(1-x*x))^0.5 * 1 };
draw (axis cs:1,-0.07,1)--(axis cs:1,0.07);

I had some trouble running your code (compatibility issues) but now it should work. I think the answer is simply that you missed a * in {x^2(1-x^2)-y^2};.

Usually x^2 is implemented using exp(2*log(x)) which can't handle negative numbers.
