Colouring between curves and cutting curves

Hi, I have made this in Matlab:

Now i want to colour the region inside the circle and outside the blue curve. After i want to cut the curves so only the coloured section will be remaining. Is there a way to do this? thanks!

I'm adding my code:

 t=0:0.01:2*pi;
r=2*sin(t).*cos(t).*cos(t);
r2=sin(t);
figure
hold on
grid on
polar(t,r);
polar(t,r2);
hold off
legend('r=2sin(t)cos^2(t)','r=sint(t)');
title('Esquisse de C et de r=sin(t)');

Can you post your code? You'll probably want to use fill with your points defined by the red and blue curves between -0.5 and +0.5, which probably has a convenient polar representation.

It would likely be easiest to use the patch function, but ‘easy’ is relative. Another possibility is the area function. I don’t know which would be most appropriate here.
