Hey guys,(adsbygoogle = window.adsbygoogle || []).push({});

I would like to get some general form of recursive formula

let f(s) = (a+bs)/(c+ds)

given this I would like to get nth composite function of f

i.e the general form of f^n(s)= fofofofofo........of(s) (nth composite)

I can conjecture that the form of f^n(s) would be the same form with f(s) like

f^n(s) = (α+βs)/(γ+δs)

and α,β,γ,δ are would be expressed as function of a,b,c,d and n

So, I would like to get the general from of α,β,γ,δ with the function of a,b,c,d and n.

Thanks
