摘要
等差、等比数列的前n项和易求,而一般数列的前n项和是不太容易求的,本文介绍利用微积分知识求数列的前n项和公式的一些方法,并给出一些结论。
It is easy to seek the sum of the first N terms of arithmetic and geometric series but hard to get that of general ordered series . The article introduces some methods of seeking the sum of the first N terms of sequence by using differential-integration and comes to some conclusions.
