Plotting https://ask.sagemath.org/question/8555/newtons-cubic-fractal-help-plotting/I'm solving newton's cubic for all the black points that occur within the fractal:
I have the code:
LA(x) = x - (x^3.0-1)/(3.0*x^2.0)
S = solve(LA==0,x)
for s in S:
solve(LA == s.rhs(),x)
and i want to take all those points I'm generating and plot them in a scatter plot. I think I have to use an array? Can anyone tell me exactly how I tell sage to put these points in an array then plot them? Thanks everyone for your help

So the function turns out to be F(x) = x - (x^3-1)/(3x^2). Is there a way to find a majority of the points (where x is undefined as in the Newton cubic fractal photo aka the black points) using Sage?rower9911Mon, 12 Dec 2011 22:05:24 +0100https://ask.sagemath.org/question/8548/
