周期函数的最小正周期在傅里叶级数计算中的作用

The Effect of Minimum Positive Period of Periodic Function Fourier Series' Calculation

证明了周期函数的傅里叶级数与积分区间长所取最小正周期的倍数的无关性 。

This article is to verify that Fourier series of periodic function is irrelevant to the multiple of minimum positive period which is obtained according to the length of integral interval,thus simplifies the calculation.\;
