摘　　要：本文在不定积分的基本方法的基础上,归纳总结并探究出关于三角函数的不定积分的具体方法。通过经典例题,展示各种方法的主要解题步骤,并说明了不定积分的问题往往会通过多种方法求解,在实际解决问题过程中,要根据实际题目来确定解题方法。In this paper, the concrete method of indefinite integral of trigonometric function will be summarized on the basis of the basic method of indefinite integral. Through a classical example, it shows the main steps of various methods, and explains that the problem of indefinite integral is often solved by many methods. In the process of solving the problem in practice, the method of solving the problem should be determined according to the actual integral problem.
