I've graphed two polar curves and would like to shade the region inside one and outside the other. When I select the two equations and then select Integrate
from the Equation menu, I get the error message
Cannot integrate the difference between the selected graphs.
It seems simple. Why can't Grapher do it?
In case it makes a difference, the two equations are r = 6
(a circle) and r = 6 - 6 sin(theta)
(a cardioid). I want to shade the region inside the cardioid but outside the circle.

Grapher can do it. Using the conjunction
r > 6 & r < 6 - 6 sin (theta)
, we get the following
