May23 comment How to prove Gauss's Digamma Theorem?@M Turgeon I can understand it's proof,Thank you again!en,I am a Chinese student,My English is poor,I will do my best to understand your words. May22 accepted How to prove Gauss's Digamma Theorem? May22 comment How to prove Gauss's Digamma Theorem?@M Turgeon Thank you very much! I think it's helpful, but I can't find a simple proof. May21 asked How to prove Gauss's Digamma Theorem? May17 answered Sum of reciprocals of squares of the form $3n+1$? May16 comment how to evaluate $\lim_{x \to \infty}(1+4/x)^\sqrt{x^2+1}$TMM I think it is easy to prove $$\underset{\begin{smallmatrix} u\to 0 \\ v\to \infty \end{smallmatrix}}{\mathop{\lim }}\,{{\left( 1+u \right)}^{v}}={{\mathrm{e}}^{\underset{\begin{smallmatrix} u\to 0 \\ v\to \infty \end{smallmatrix}}{\mathop{\lim }}\,uv}}$$so I don't give a proof.Here I present a wide range of formulas,it can solve the problem,and I think you can Understand it and prove it.
