摘要: 本文主要介绍了一类被积函数为
的不定积分问题的求解方法并证明了在不同的方法求解下所得到的任意两个原函数之间只相差一个常数；有效地回答了在适当的假设下，任意两个原函数是等价的结论。最后，我们给出了被积函数为
情形下不定积分的原函数的表达式。
Abstract:
This paper mainly introduces the solution of a class of indefinite integral problems with the integrable function
, and proves that there is only one constant difference between any two arbitrary functions obtained by different methods. The conclusion that any two arbitrary functions are equivalent under the appropriate assumption is effectively answered. Finally, we give the expression of the original function of indefinite integral when the integrable function is
.
