comment Prove $\lim_{n \to \infty} \frac{\Gamma(n+1/2)}{\Gamma(n)~n^{1/2}}=1$
I got $\lim_{x \to \infty}(1+a/x)^{x+a-1/2}*e^{-a}=1$, right?

excellent, thank you. didn't think about using the Stirling's formula in the way you showed. now I know, thanks again!

that's what I thought, though I couldn't make the difference, because I dissected both into elements. thanks!
