You can get an arbitrarily good approximation with the Taylor series representation of [itex]ln(x)[/itex] by integrating term by term the sequence form of [itex]1/x[/itex].

What do you mean with closed formula? What functions are you allowed to use?

Ln(x) has a singularity at x = 0, so you can't have a Taylor series around 0.
