| 摘 要： | 对于比较复杂的函数进行求导或积分运算时,常常需要对其变形化简.通过实例分析,指出这种变形化简有可能影响到最终因此而求出的"导函数"或"原函数"定义域与最初所给函数的定义域不相一致,并给出解决此问题的应对方法.

| Abstract: | In order to find derivatives or to seek indefinite integrals of complex functions, simplifying or deforming are needed. These proeesses may sometimes result in change of intervals which ＂derivative＂ or ＂primary function＂ are defined. Solutions are proposed to fix these problems. |

| Keywords: | domain derivative primary function definite integral continuity |
