I meant analytic functions.

comment Expression for function's period
Yes. I want a constructive formula that gives an actual expression or encodes an algorithm of how to find such period.

I am interested in operator that returns (minimal) period for analytic functions.

comment Reverse search for rational function
Well I meant can there be such function of u and v that gives the polynomial's coefficients irrespective of the method of how u and v are given.

comment Reverse search for rational function
If we find at leat one pair of polynomials we can cancel the common factors out of course so the task is ti find at least one such pair or the function Q directly.

comment Reverse search for rational function
Yes, of course. I meant the simplest form of that function.

comment Tractrix-like curves
Interesting, is it possible to have an explicit expression for alpha?

comment Tractrix-like curves
Oh now I see the result of the expression should be the $(x,y)^T$ vector. It is just omitted but there should be an equality sign.

Thanks but still cannot understand how an equatioc can be without equality...

Ok, alpha is the vector? But where is the equation? I see no equality sign...

comment Please suggest a sequence with the following properties
$\sum_{n=0}^{\infty} \frac1{n!}$ will converge to e (it is exp(1)), and it is a trivial case to take $a_n=\frac1{e n!}$

You said there is a parametric equation, but there is no equation sign in it.

I do not see x and y, only f, g and alpha and there is no equation....

It should be equal to zero?
