plotimplicit or implicitplot draws curves or
surfaces defined by an implicit expression or equation.
If the option unfactored is given as last argument, the
original expression is taken unmodified. Otherwise,
the expression is normalized, then replaced by the
factorization of the numerator of it's normalization.
Implicit graph: plotimplicit implicitplot
Each factor of the expression corresponds to a component
of the implicit curve or surface. For each factor,
Xcas tests if it is of total
degree less or equal to 2, in that case conic or
quadric is called. Otherwise the numeric implicit solver
Optional step and ranges arguments may be passed to the numeric
implicit solver, note that they are dismissed for each component
that is a conic or a quadric.
