摘要
文章主要基于函数对不定积分运算的封闭性讨论了待定系数法在不定积分中的运用。几个经典实例说明了几类需要运用多次分部积分法的不定积分,由待定系数法可以直接得到。结果表明,该方法丰富了计算不定积分的思路。
This paper mainly discusses the application of undetermined coefficient method in indefinite integral based on the closeness of function to indefinite integral operation.Several classical examples show that several kinds of indefinite integrals which need to be solved by multiple partial integration method can be obtained directly by the undetermined coefficient method.The result shows that this method enriches the idea of calculating indefinite integral.
