摘要
本文主要研究三角函数系,对其性质进行推广,并将得到的结论应用于求解定积分.例题的求解过程表明:利用本文的结论求解定积分确实可以简化计算.
In this paper,the trigonometric function system is studied, and its properties are generalized,thenthe conclusions are used to solve definite integral. From the solving process of the examples, we can see that it can really simplify the calculation by using the conclusions.
