No, at most two constants. The domain of the integrand is disconnected ## x \in (0,1)\cup(1,\infty)##. It's possible to have one constant for the first connected component and a different constant for the other.
Since one of them actually hid itself from me, proves they are well-hidden, as I said. :biggrin:
hi arildno. didnt understand the last sub :(
I dont know if u need this or not, but

Substitution1: u=ln(x)

Substitution2: t=1/u

Makes it much easier.😁
