 Dec8 awarded Caucus Dec8 accepted How to construct a polynomial from a radix-term? Dec8 comment How to construct a polynomial from a radix-term? Ah yes, that makes sense. I'm sorry for my confusion. Dec8 comment How to construct a polynomial from a radix-term? That was a typo, it should have been $\alpha\in\mathbb Q\setminus\{0\}$. I'm a bit confused about how you explain the translation that makes a polynomial $p'$ with $p'(\alpha^{-1})=0$ from a polynomial $p$ with $p(\alpha)=0$. Your explanation does not really enlightens me. Maybe that's just because I am a bit hungover. Dec8 comment How to construct a polynomial from a radix-term? I'm afraid I might have misunderstood something, but what guarantees that $\alpha\in\mathbb Q\{0\}$? Isn't $\alpha$ the value of an arbitrary algebraic expression with $\alpha\neq0$? Dec8 comment How to construct a polynomial from a radix-term? What do you do if we take a negative power over a subterm? Dec8 comment How to construct a polynomial from a radix-term? How can we prove that for every polynomial with integer coefficients $\sqrt 2$ is a root of, $-\sqrt 2$ is a root, too? Dec8 comment How to construct a polynomial from a radix-term? @HenningMakholm Ah, that makes sense. Thank you for pointing out the correct term. Dec7 asked How to construct a polynomial from a radix-term? Nov27 comment Showing that $\lim_{x\to\infty}\left(\sqrt{x^2+c}-x\right)=0$ I feel dumb now. Nov27 accepted Showing that $\lim_{x\to\infty}\left(\sqrt{x^2+c}-x\right)=0$ Nov27 revised Showing that $\lim_{x\to\infty}\left(\sqrt{x^2+c}-x\right)=0$ add condition on c Nov27 asked Showing that $\lim_{x\to\infty}\left(\sqrt{x^2+c}-x\right)=0$ Nov11 comment How to prove that $\lim\limits_{x\to0}\frac{\sin x}x=1$? In a triangle $ABC$ with right angle in $ACB$ we define $\sin BAC=BC/AC$. This is the “geometrical” definition for $\sin$ we used.
