3.1 Ordinary Generating Functions
吉太拍 (知不知，尚矣)
Find [z^N] for each of the following OGFs: 引自 3.1 Ordinary Generating Functions 92 由OGF求coefficient有两种方法：一种是泰勒展开；另一种是由已知OGFs进行运算。
taylor series 1/(1 - 3 z)^4
SeriesCoefficient[1/(1-3z)^4, {z, 0, n}]
SeriesCoefficient[(1-z)^2ln(1/(1-z)), {z, 0, n}]
SeriesCoefficient[1/(1-2z^2)^2, {z, 0, n}]
taylor series 1/(1-2z^2)^2
