Still no response to this problem, either

Generally speaking: Sage Days somewhere (IPAM in this case) tend to
drop the amount of people that deal with problems on the mailing list
before, during and after the work shop because people have to travel,
get ready for the workshop and
I don't know how to fix it so that parametric_plot works. However, the
following workaround at least gives you a plot:
sage: a = RR(1729^(1/3))
sage: f1 = lambda x: RR(real((1729 - x^3)^(1/3)))
sage: f2 = lambda x: RR(real(-(-1729 + x^3)^(1/3)))
sage: L1 = [(x,f1(x)) for x in
