But I can't figure out any good way to solve this.
Is there a special theorem or method to solve such limits?
Answer
Why not elementary? n(\ln(n+2)-\ln n)=\ln(\frac{n+2}{n})^n=\ln(1+\frac{2}{n})^n \to \ln e^2=2
I have injection f \colon A \rightarrow B and I want to get bijection. Can I just resting codomain to f(A)? I know that every function i...
