Taylor Series
The digamma has a rational zeta series, given by the Taylor series at z=1. This is
- ,
which converges for |z|<1. Here, is the Riemann zeta function. This series is easily derived from the corresponding Taylor's series for the Hurwitz zeta function.

Famous quotes containing the words taylor and/or series:
“I counted two and seventy stenches,
All well defined and several stinks!
Ye Nymphs that reign oer sewers and sinks,
The river Rhine, it is well known,
Doth wash your city of Cologne;
But tell me, Nymphs! what power divine
Shall henceforth wash the river Rhine?”
—Samuel Taylor Coleridge (17721834)
“The womans world ... is shown as a series of limited spaces, with the woman struggling to get free of them. The struggle is what the film is about; what is struggled against is the limited space itself. Consequently, to make its point, the film has to deny itself and suggest it was the struggle that was wrong, not the space.”
—Jeanine Basinger (b. 1936)
