Methods for summation of divergent series are sometimes useful, and usually evaluate divergent geometric series to a sum that agrees with the formula for the convergent case :$\backslash sum\_^\backslash infty\; ar^k\; =\; \backslash frac.$ This is true of any summation method that possesses the properties of regularity, linearity, and stability. ==Examples== In increasing order of difficulty to sum: *1 − 1 + 1 − 1 + · · ·, whose common ratio is −1 *1 − 2 + 4 − 8 + · · ·, whose common ratio is −2 *1 + 2 + 4 + 8 + · · ·, whose common ratio is 2 *1 + 1 + 1 + 1 + · · ·, whose common ratio is 1. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Divergent geometric series」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
