 Mar 3 revised Is there a totally ordered set we can map any other totally ordered set to? added 2 characters in body Mar 3 asked Is there a totally ordered set we can map any other totally ordered set to? Jan 1 awarded Yearling Dec 8 awarded Caucus Dec 8 accepted How to construct a polynomial from a radix-term? Dec 8 comment How to construct a polynomial from a radix-term? Ah yes, that makes sense. I'm sorry for my confusion. Dec 8 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. Dec 8 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 $\alpha\neq0$? Dec 8 comment How to construct a polynomial from a radix-term? What do you do if we take a negative power over a subterm? Dec 8 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? Dec 8 comment How to construct a polynomial from a radix-term? @HenningMakholm Ah, that makes sense. Thank you for pointing out the correct term.

In a triangle $ABC$ with right angle in $ACB$ we define $\sin BAC=BC/AC$. This is the “geometrical” definition for $\sin$ we used.
