 May14 comment A suspicious way to conclude convergence Yes. I thought a real divergent sequence had to go to $\pm\infty$. May13 accepted A suspicious way to conclude convergence May13 comment A suspicious way to conclude convergence Indeed, $S$ neither converges nor diverges. May12 asked A suspicious way to conclude convergence May7 comment Is there a need for another integration technique? Next time I'll know better than to not draw the freaking region. =D May6 accepted Is there a need for another integration technique? May6 asked Is there a need for another integration technique?

Based on your answer, I have another idea: when $a$ is $1$, $\omega\mapsto\omega^k$ is invertible if and only if $k$ is invertible modulo $n$; but the set of such numbers is an abelian group, so I could argue $\mathrm{Gal}(F)\simeq\mathbb Z_n^\times$. Sep20 asked Splitting field of a slightly general polynomial Jul25 comment Finding a pair of elements to satisfy an inequation @JackSchmidt I had an insight as soon as I read your comment. A field is a domain, and this one has at least two non-zero distinct elements. Pretty easy, I should've thought of that by myself. Thanks.
