Can anyone help me with this problem?
Find the area shaded by the cardiods r=2+2cos(x) and r=2-2cos(x).
I started out with that, but then noticed 4 way symmetry. If I am wrong, then Soroban is wrong as well. I am not so sure we are wrong.
I also checked this with tech and got the same as Soroban and I. Therefore, I am going with our solution. Even thought the solutions are close.
