针对学生在复合函数求导过程中容易混淆df[g（x）]/dx、f＇[g（x）]和f＇[g＇（x）]三种类型求导的问题，通过两道典型例题，帮助学生理解df[g（x）]/dx、f＇[g（x）]和f＇[g＇（x）]的确切含义．

英文摘要：

Students are easily confused with the three kinds of composite and derivative functions df[g（x）]/dx、f＇[g（x）] and f＇[g＇（x）].Through two examples, this paper provides a way to helps students to understand the exact meaning of these functions.
