Polylogarithm python
WebPolylogarithm and Geometric Progression. Polylogarithm is connected to the infinite geometric progression sum \operatorname {Li}_0 (x)=\sum_ {n=1}^\infty x^n=\dfrac {x} {1-x}. Li0(x) = n=1∑∞ xn = 1−xx. We can divide by x x and differentiate with respect to x x to get \operatorname {Li}_ {-1} (x)=\sum_ {n=1}^\infty nx^n=\dfrac {x} { (1-x ... WebMay 31, 2009 · rashore. 1. 0.
