@Ashot typo, agree it's a real problem. Fixed and suggested another approach.

comment Transposition $s=4t+\ln(1−t)$
Given this is a homework problem, likely would've been better to hint (even extensively) instead of solving for them.

comment Square Root Yields Different Result After Unit Conversion
$\sqrt{\text{sec}^2} = \text{sec}$, but $\sqrt{\text{sec}} \neq \text{sec}$. Adjust the units and you will be ok -- you need to take square roots in the unit factor

comment Given $P\colon\mathbb{R} \to \mathbb{R}$ , $P$ is injective (one to one) polynomial function. Prove formally that $P$ is onto $\mathbb{R}$
Didn't you say there is a theorem that all continuous and monotonic functions have an inverse function -- and yours must be both since it is a 1-to-1 polynomial? Existence of the inverse implies it is defined on the entire domain, thus proving that your function maps to the entire codomain?
