(五) 关于求不定积分 (一) 一般高等数学教科书里,关于原函数与不定积分的概念,大多如下叙述: (1) 已知定义在某一区间上的一个函数f(x)。如果有这样的函数F(x),使得在已知区间上的任何一
(5) About Indefinite Integral (1) In general higher mathematics textbooks, the concepts of the original function and indefinite integral are mostly described as follows: (1) A function f(x) defined in a certain interval is known. If there is such a function F(x), making any one of the known intervals
