摘要
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.
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.
