摘要
本文总结归纳了常见的被积函数是三角函数的定积分的计算技巧,主要研究了形如∫0πcosmxsinnxdx(其中 为正整数)(1)的一类定积分,得到了相应的一个计算公式,并举例说明了公式的实用性和便捷性。
This paper sums up the common calculation skills of definite integral of trigonometric functions. A class of definite integral with the form of ∫0πcosmxsinnxdx (where  are positive integers) is studied, and a corresponding calculation formula is obtained. Moreover, some examples are given to illustrate the practicability and convenience of the formula.
