周期函数的数值积分方法

The Numerical Integration of Periodical Function

本文就周期函数的数值积分 ,提出用梯形求积公式计算 ,不仅合理、简单 ,而且具有非常高阶的精度。

In this essay,the author puts forward an opinion that using trapezoidal integration to caculate the numberical integration of periodical function is not only resonable and easy, but also highly precise.
