**Reiny**, Tuesday, June 17, 2014 at 9:20pmI saw this question and have not been able to get a handle on it

we know that ln(x) has an expansion formula

but it only good for |x-1| < 1

so we could create a series of terms

= 1/(x+1) ( (x-1) - (x-1)^2 /2 + (x-1)^3 / 3 - .... )

but to integrate each term would be a mess

- even Wolfram, usually very dependable, could not handle it.
