=============
All: I would like to shade the area outside of the circle Sqrt[3] and
inside the lemniscate r^2=6Cos[2 t]. Can this be done using PolarPlot
and mesh functions or is something else needed?
PolarPlot[{Sqrt[3], Sqrt[6 Cos[2 t]], -Sqrt[6 Cos[2 t]]}, {t, 0, 2 Pi}]
Shows the curves without the shading. Jon
