利用复变解析函数求三角级数的和函数

Complex Analytic Function Utilized in Sum Function Evaluation of Trigonometric Progression

我们在研究三角级数的系数时,能够证明这些级数的收敛性,但怎样求出这些级数的和呢?本文提出了求和函数的一种方法。

Generally,when researching coeffcient of trigonometric progression, we can only demonstrate convergence feature of these progressions but not evaluation their sum. This paper puts forward the solving ways to it.
