 Mar 20 comment uniformly continuous functions in [0,∞) @t.b. Nice, thank you for providing the missing parts to my answer. : ) Mar 20 answered uniformly continuous functions in [0,∞) Mar 18 comment A question about an $n$-dimensional subspace of $\mathbb{F}^{S}$. @spohreis: What is $W$? Mar 18 revised If coprime elements generate coprime ideals, does it imply for any $a,b\in R$ that $\langle a\rangle+\langle b\rangle=\langle \gcd (a,b)\rangle$? added 9 characters in body Mar 18 revised Presumably Simple Laplace Transform Question Typo in formula corrected. Mar 18 comment Presumably Simple Laplace Transform Question @JonaGik Glad I could help : ) Mar 18 answered Presumably Simple Laplace Transform Question Mar 18 revised Union of the conjugates of a proper subgroup added 123 characters in body Mar 18 comment Union of the conjugates of a proper subgroup @ArturoMagidin Thanks for telling me. I think I'll just delete my answer for now. I might edit it and repost it at some later point. Mar 18 comment Proving $|K| = p^n \Rightarrow \operatorname{char}(K) = p$ Thank you! That's much nicer than what I wrote!

Mar 17 comment The solution set of the equation $|2x - 3| = - (2x - 3)$ @FaMu Yes, it does! : ) Mar 17 comment How to compute $\sum\limits_{k=0}^n (-1)^k{2n-k\choose k}$? @BrianM.Scott No, I wrote "like the Fibonacci numbers ... but with alternating signs" : ) Mar 17 comment How to compute $\sum\limits_{k=0}^n (-1)^k{2n-k\choose k}$? It looks like the Fibonacci numbers $$\sum_{k=0}^{\lfloor \frac{n}{2} \rfloor} {n - k \choose k} = F(n+1)$$ but with alternating signs. Mar 17 answered How to prove $\lim_{n\rightarrow \infty} {a^n \over n!}=0$ Mar 17 answered Euler method classification Mar 17 comment If A is a subset of B, then the closure of A is contained in the closure of B. I thought so : )
