plotting a conic section by knowing its standard equation

[Lorenzo Bercelli]

hello everybody, I got a very silly question: what's the best way to plot a conic section on a plane if I have its standard equation (e.g.: x^​2^+y^^2​​=1)? I've tried plot but it needs a univariate expression, and I haven't been able to find a method to transform the expression into f(x) = \pm sqrt(1-x^2)

To get a set of functions to plot, you would use solve(), like
solve(Eq(x**2 + y**2, 1), y). This will return two solutions, which
when plotted simultaneously, should give a full circle.

An easier way is to use plot_implicit(), which doesn't require
solving, and will work even for equations that can't be solved by
solve().
