I think differentiability implies continuity.

comment $QQ$-plot - Why do we choose the empirical distribution $F_n(x) = \frac {\#\{y \in S \mid y \le x\}} n$, $S$ is sample, for comparison with normal?
Just to mention that there is another SE site for statistics: stats.stackexchange.com

comment Correspondence between an order of rational function field and a Dedekind cut
Thanks. Then where does the $a$ come from? It seems to me that $X>_{\mathbb{R}(x)}x\iff X-x>_{\mathbb{R}(x)}0\iff -x >_\mathbb{R}0 \iff x<_\mathbb{R} 0$.

comment How prove this inequality $(a^2+bc^4)(b^2+ca^4)(c^2+ab^4) \leq 64$
Maybe different patterns of lines, if that's convenient for you.

comment Set of critical points of polynomial: why finite
When you say a polynomial defined on $\mathbb{R}^n$, does it mean a multivariate polynomial with $n$ variables?

Can you use other colors? Since many people have protanopia or protanomaly (like me).

comment Find derivative of $f(x)=(x+2)^{(x-1)}$
OK, I get it. It has nothing to do with the logarithm.

Sounds like the same as $f$ except for the positiveness.
