yes, 0 is a singularity, in fact, but some books consider the value of this residue 1: I would understand the real reason...

Parisse, please, there is a way in Prime (and emulator) to get coefficients ak and bk of the Laurent Series (or the whole series), to confront result with residues in some case?

Thanks a lot for kindness
