comment Find the asymptote of an experimental dataset
@leftaroundabout , I am 100% sure the curve I am showing has an asymptote, because this is a stand-in for my experimental data and I created it with an asymptote: $y(x)=3/(x+1)+2+0.2rand()$. --- I would like to know whether there is any technique that doesn't involve fitting a function that would allow me to estimate this asymptote

comment Approximating $\tanh(B\sqrt{A} )$ for small $A$ and arbitrary $B$ by correcting for asymptotic behaviour of $\tanh$
I just found this question, I think that could be helpful for this particular case: math.stackexchange.com/questions/107292/…

comment Approximating $\tanh(B\sqrt{A} )$ for small $A$ and arbitrary $B$ by correcting for asymptotic behaviour of $\tanh$
How did you come up with $\tanh x \approx 1 - e^{-1.48x}$? If there is some strategy to that which I can also apply to the complete function which contains the $\tanh$ that would be perfect. Using the $\tanh$ itself is not an option because I need to solve an equation of the type $A + \tanh(B \sqrt{A})=1$ explicitly for $A$.

Strictly it can be anywhere between 0 and $\infty$, but the range I am interested in is roughly 0 to 50.

comment Why does the moment of approximation matter for the end result?
@AntonioVargas - I have tried the Newton's method approach for the full equation I am working on (the one here is just a minimal example to reproduce the behaviour) and it does indeed give a somewhat better approximation, although at the expense of having a significantly bigger equation. Thanks!

So would it be appropriate then to take again a Taylor series of (4) because this function is no longer linear in $a$? Because doing that would indeed result in the same answer as (3)

comment Approximations other than taylor series and pade approximation
Yes, I would like to have an approximate solution to get a feel for the way the result scales with $K_i$ and $Q_i$. Without having to scan a whole range of these parameters.
