Re: [sage-support] Plotting algebraic curves

Parametric plots won't work for general algebraic curves. But I'm also not sure how to implement the transformation into a circle. I'll look at the documentation for plots. Fernando On 3/1/2020 8:50 AM, David Joyner wrote: On Sat, Feb 29, 2020 at 5:29 PM Fernando Gouvea

[sage-support] Plotting algebraic curves

(Repost, as the first message seems to have ended up in the wrong thread.) Some years ago in a book review, David Roberts had the idea of plotting an algebraic curve using the transformation  (u,v) = (x,y)/(r^2  + x^2  + y^2 )^1/2 , which transforms the plane into a circle and makes it easy to

Some years ago in a book review, David Roberts had the idea of plotting an algebraic curve using the transformation (u,v) = (x,y)/(r2 + x2 + y2)1/2, which transforms the plane into a circle and makes it easy to visualize the projective completion of the curve. You can see some of his plots at http
