Can Sage compute the projective dual of a plane curve?
Not at the moment. I'll open an enhancement ticket for this as a
requested feature. It looks like an interesting problem. What kind of
base rings do you care about?
I'm playing with a family of plane curves with rational coefficients in
the complex projective plane. So rational or complex numbers would be
enough for me to test examples. In a perfect world I'd be able to
specify a family using rational functions of arbitrary constants
(something like a x^2 + b/(a-1) y^2), and compute the projective dual in
terms of those constants.
