Hmm, that is a good question. We certainly support implicit plotting and polar plotting, but it doesn't seem that we do together. The way that polar plotting is supported is basically that the data is switched to [y*cos(x),y*sin(x)] before actually rendering. Now, you can do something like this: var('x,y') r = sqrt(x^2+y^2) theta = arctan2(y,x) implicit_plot(r^2==5-4*cos(theta),(x,-4,4),(y,-4,4),aspect_ratio=1) https://sagecell.sagemath.org/?q=mvmspq But obviously that is not ideal. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
