If nevertheless we would attempt to define the notion "indefinite," then that's a paradox because if we succeed, then it is defined, which contradicts its meaning – its indefiniteness – and the word "indefinite" means that it cannot be defined.

但是如果我们试图界定概念"无限期"，那么，这样的悖论，因为如果我们成功，那就定义这与它的意义--其不确定性和"无限期"的意思，所以无法确定。

This article has sorted out the data of indefinite integral concept in common use, and has analyzed the features of three methods of indefinite integral in common use: the first substitution method of integration, the second substitution method of integration, and integration by parts.

因为，(x2)′=2x，(x2+1)′=2x，(x2+2)′=2x，(x2+c)′=2x所以x2，x2+1，x2+2，x2+c均为2x的原函数。由此得出：一个函数若有原函数存在则有无数个原函数存在，且任意两个原函数之间相差一个常数。

However, to have meaning, the process of definition has to be defined; this definition would be a self-referential quasi-infinite and continuous process of establishing borders that create the indefinite beyond that establishes borders creating the indefinite beyond that establishes borders… which means, wholeness would continuously and forever fail to define itself while succeeding to define something – anything but itself.

但是，具有意义，过程定义加以界定；这个定义是自我参考准无穷正在建立和不断创造无限超越国界，确定边界，确定边界以后创造无限：：即整体性将无法持续下去，而成功的定位，确定了-害而本身。
