Moreover, this surface is immersed in a solid torus like
sage: p1 = parametric_plot(( a*(R + x)*cos(z), a*(R + y)*sin(z), a*y ),(p,0,2*pi),(q,0,2*pi))
for some a and R.
How can one plot a section of the surface by a plane with Sage?Fri, 14 Nov 2014 21:55:50 +0100https://ask.sagemath.org/question/24867/plotting-a-plane-section-in-sage/Comment by tmonteil for <p>Suppose I have a parametric surface given by three functions in two variables.

https://ask.sagemath.org/question/24867/plotting-a-plane-section-in-sage/?comment=24886#post-id-24886Some information seems missing. Evaluating p1 does not work for me. How are p and q related to x,y,z ?Sun, 16 Nov 2014 19:41:14 +0100https://ask.sagemath.org/question/24867/plotting-a-plane-section-in-sage/?comment=24886#post-id-24886Comment by uglychamaeleon for <p>Suppose I have a parametric surface given by three functions in two variables.

https://ask.sagemath.org/question/24867/plotting-a-plane-section-in-sage/?comment=24888#post-id-24888@tmonteil Sorry for misleading notation. X, y and z are functions in two variables p and q.Mon, 17 Nov 2014 00:36:39 +0100https://ask.sagemath.org/question/24867/plotting-a-plane-section-in-sage/?comment=24888#post-id-24888
