Quote: \( AS(x+1) = 1 + x^2 + \frac{1}{2}x^3 + \frac{4}{3}x^4 + \frac{19}{12}x^5 + \cdots \)Wait... the series above only works for even approximants, I also got:
\( AS(x+1) = -x - x^3 - x^4 - \frac{29}{12}x^5 - \frac{13}{4}x^6 + \cdots \)
for odd approximants, and they can't both be right... what am I doing wrong?
