P.<x,y,z> = PolynomialRing(QQ)
and I've eliminated the variable `t` in an ideal generated by several polynomials to obtain an implicit function in just `x` and `y`. I'd like to plot this function. But the `plot` method, applied to an ideal in just two variables, produces the error:
ValueError: Variable 't' not found
So either I need somehow to introduce this variable into the plot, or pull the function out of the polynomial ring so that it can be plotted as a function of real variables with `implicit_plot`. But I'm not sure how to do either...any advice would be most helpful!AlasdairMon, 25 May 2015 03:57:20 +0200https://ask.sagemath.org/question/26931/
