Plot Inequality Area of polar equation? Using Wolfram Alpha or Matlab?
I want to plot or graph the inequality area between two polar equations.
For example, I'd like to plot the area between 
and 
.
I am very familiar with both Matlab and Wolfram Alpha, however I can't figure out how to do this. Any suggestions?

Construct an indicator variable which is 
in the area in question and 
elsewhere on a 
grid (or 
grid if you prefer). Now do a density plot (a colour 3D plot looking down from above) of the indicator variable.
