 Nov 6 revised Finding an asymptotic for the sum $\sum_{p\leq x}p^m$ added 570 characters in body Nov 6 comment Finding an asymptotic for the sum $\sum_{p\leq x}p^m$ @Jose, where'd you get this from? Nov 6 revised Finding an asymptotic for the sum $\sum_{p\leq x}p^m$ added 83 characters in body Nov 6 revised Finding an asymptotic for the sum $\sum_{p\leq x}p^m$ added 83 characters in body Nov 6 revised Finding an asymptotic for the sum $\sum_{p\leq x}p^m$ added 78 characters in body Nov 6 answered Finding an asymptotic for the sum $\sum_{p\leq x}p^m$ Nov 5 comment {$\int_{[1/n,1]}f$} to converge and yet $f$ is not $L$-integrable over $[0,1]$ Ah, I get it, it has note one big spike but denumerably many - one for each $n$. Nov 5 comment {$\int_{[1/n,1]}f$} to converge and yet $f$ is not $L$-integrable over $[0,1]$ @JonasMeyer: $f$ is just some function, how can it depend on $n$? Oct 28 comment Space with non-convergent Cauchy sequence What is the definition of a "convergent space" and a "Cauchy space"? Do you mean "sequence" instead of "space"? In that case, try constructing a space in which nothing is Cauchy? Oct 23 comment Prove that $\lim_{n\to \infty}\left (1+\frac{1}{2^n}\right)^{2^n}$ exists @Badshah, then lookup a proof for this equivalence and apply it to your problem. Oct 22 awarded Nice Answer Oct 21 comment Is this probability question wrong to begin with? Short answer: yes. Longer answer: suppose any of the answers is correct (literally: try them all), and derive a contradiction for each of them. Oct 3 comment Why is the sequence $(\langle x_n,a \rangle)$ Cauchy when $(x_n)$ is? what is $a$ exactly? Oct 3 comment Why are all polynomials with real roots factorizable? @GerryMyerson, but not into linear binomials Oct 2 comment Project in computer science and mathematics. There is such a thing as "computational group theory", but I don't think it is a very fruitful subject, though I could be wrong. Sep 29 comment Proof the following proposition: for all $n \geq 0, \mathrm{fib}(n) \leq n!$ A classical Brian M. Scott answer, correct and complete. Sep 25 comment Why is $i! = 0.498015668 - 0.154949828i$? Strictly speaking, under the usual definition the factorial is only defined for natural arguments, so you will have to use a generalized definition for $i!$. Sep 24 comment Can I integrate both sides of this equation? Note that it is in general incorrect to differentiate both sides of an inequality. Sep 22 comment How to divide currency? @RodCarvalho: Sure enough, we as mathematicians can shed some light on various optimality conditions, and previous solutions to this problem. Repeating the problem statement in mathy words is not an answer at all. Sep 22 comment Statements in Euclidean geometry that appear to be true but aren't Uhm... isn't this one true?
