cyclic rational inequalities $\frac{1}{a^2+3}+\frac{1}{b^2+3}+\frac{1}{c^2+3}\leq\frac{27}{28}$ when $a+b+c=1$

Calculus of $ \lim_{(x,y)\to (0,0)} \frac{8 x^2 y^3 }{x^9+y^3} $

How would you characterise the inverse image of this polynomial equation?

Why are rational functions called "rational"?

Does there exist a function $f_{\Box,\Box}(\Box)$ making the formula $a + (b \oplus c) = (f_{b,c}(a)+b) \oplus (f_{c,b}(a)+c)$ true?

ّFind $x$ such that $ \frac{1}{x^2} + \frac{1}{(3-x)^2} = \frac{104}{25}$.

Verify my proof of divisibility of a rational fraction

Does there exist a nontrivial rational function which satisfies $f(f(f(f(x))))=x$?

When does $f(X) = g(X+1)-g(X)$ where $f, g \in \mathbb{C}(X)$?

Why aren't the functions $f(x) = \frac{x-1}{x-1}$ and $f(x) = 1$ the same?
