(log( (a-1)/a ) - log(a-1) + log(a)).full_simplify()

works for me.

By the way, I have a question which is far away from Sage : in the sentence
"
Help will be appreciated.
"
Is "appreciated" a false-friend for the French expression "appréciée" ?
Can one use "appreciated" in English in that context ?


Have a good night
Laurent
