摘要
函数的可导性是数学分析中所研究的主要性质,对于函数|f(x)|,f2(x)的可导性与函数f(x)的可导性一般没有必然的联系,但是在一定条件下,它们却有着密切的联系。通过论证,得出了函数|f(x)|,f2(x)与函数f(x)之间的可导关系,并给出相应的结论。
The derivable nature of function is the main nature that people study in mathematical analysis. The derivable nature about the fuctions of |f(x)| ,f^2 (x) and f(x) isn' t related in general, but in some special case, they are related. The paper studies the derivable relation between the fuctions |f(x)| ,f^2 (x) and f(x).
