I did this exact thing with a same problem on the same application that you used and got the answer wrong. I am extremely frustrated because I don't understand this at all and I am on the last day of class.
Hello thanks for your video, do you have a hint for me how to prove ~A↔ B, ~B ↔ C, ~C ↔ A ╞ λ ? I already used the Df rule but I still cannot see how to show that an absurdity follows... Help would be much appreciated... Thank you!
