Can we But I don't see a clear functional equation nor anything else , to determine if the limit is Rational. -
GGavran replied to the thread Undergrad Prove that 1 + NOT (1 + NOT x) = x.We can define the function ## f(x)=1+\text{NOT}x ## and prove that ## f^{-1}(x)=f(x) ##. ## \begin{align} f(x)=1+\text{NOT}x&\implies...
