1,552,926 | For positive reals $a,b,c$, with $abc=1$, prove that $$\frac{a^3+1}{b^2+1}+ \frac{b^3+1}{c^2+1}+\frac{c^3+1}{a^2+1} \geq 3$$ I tried the substitution $x/y,y/z,z/x$, but it didn't give me anything. What else to do? Thanks. | 2015/11/30 | [

] | By re-arrangement inequality, we have
$$\sum\_{cyc} \frac{a^3+1}{b^2+1} \ge \sum\_{cyc} \frac{a^3+1}{a^2+1}$$
So it is enough to show that for positive $x$, the function
$$f(x) = \frac{x^3+1}{x^2+1}-1-\frac12 \log x \ge 0$$
as the inequality is equivalent to $f(a)+f(b)+f(c) \ge 0$.
From $\displaystyle f'(x) = (x-1)\... | There is already a full and great answer. This is only an alternative
using AM-GM instead of the rearrangement inequality:
From the AM-GM inequality we have
$$
\frac 13 \left(\frac{a^3+1}{b^2+1}+ \frac{b^3+1}{c^2+1}+\frac{c^3+1}{a^2+1} \right) \ge
\left(\frac{a^3+1}{b^2+1} \cdot \frac{b^3+1}{c^2+1} \cdot \frac{c^3+1}... |
