	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∫<sub>0</sub><sup>π</sup>cos<sup>m</sup>xsin<sup>n</sup>xdx(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。<br />
This paper sums up the common calculation skills of definite integral of trigonometric functions. A class of definite integral with the form of ∫<sub>0</sub><sup>π</sup>cos<sup>m</sup>xsin<sup>n</sup>xdx (where&nbsp;&nbsp; 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.
