In plotting two functions on the same plot, is it possible to specify two domains, one for each function?

I'm trying to graph nonlinear systems of inequalities.  INEQUAL works only with linear systems.  Someone in this forum suggested IMPLICITPLOT with the option FILLED = TRUE, but this doesn't always give the desired results since that option only gives the area between the curve and the x-axis a solid color.  What I need is the power of OPTIONSFEASIBLE, OPTIONSEXCLUDED, OPTIONSOPEN, and OPTIONSCLOSED (options available with INEQUAL) that will work with nonlinear inequalities.

I want to graph nonlinear inequalities in two variables, but  Inequal works only for linear inequalities.  How to proceed?

For the polar equation, r = 2 sin(theta), will some kind soul please give me the syntax for a parametrized plot?

On some pocket calculators if you plot two polar equations on the same graph, you can get estimates of the coordinates of the points of intersection.  Does Maple have something similar?
