Sign of $\cosh(\frac{t}{2}\cosh(\theta))\cosh(\frac{t}{2})-\cosh(\frac{t}{2}\cosh(\theta))-\cosh(\frac{t}{2})$ on $t\ge 0$ For fixed $\theta>0$ we consider the function: $f(t)=\cosh(\frac{t}{2}\cosh(\theta))\cosh(\fr...
> Key-tool: $\cosh(2x)=1+2\sinh^2(x)$ This is a nice example where computing the derivative only obscures things... Let $u=\cosh\theta$, then, for every $t$, $$f(4t)=\cosh(2ut)\cosh(2t)-\cosh(2ut)-\cosh(2t)=4\sinh^2(ut)\sinh^2(t)-1$$ hence $f(4t)$ has the sign of $g(
