Mar 30 answered 'Error term' in zeta function Mar 28 accepted Is there a general approach to solve integrals of the form $\int\frac f{f'}$? Mar 28 asked Is there a general approach to solve integrals of the form $\int\frac f{f'}$? Mar 24 accepted How to come up with the gamma function? Mar 11 comment How to come up with the gamma function? Okay. Thank you! Mar 11 comment How to come up with the gamma function? YOur first interpretion is right. But your answer shows only that the integral satisfies the recurrence relation $\Gamma(x+1)=x\Gamma(x)$ and does not show how one can derive that integral. Mar 11 comment How to come up with the gamma function? Thank you for that answer although you don't point out how one get's to $\int_0^\infty t^ne^{-1}\;\mathrm dt$. Mar 11 comment How to come up with the gamma function? Sorry. I found out that the article actually contains an answer to my question, thus I removed my post.

Feb 16 comment $y''=(y')^{3} e^{y}$, some easy way to solve this non-linear differential equation? Did you tried using Wolfram Alpha? It can also shows you a step-by-step solution.

In German, one says "stetig" to say "continuous". stetig and steady are false friends... Jan 17 revised Question about a lemma on continuity added 8 characters in body
