幂指函数型极限的讨论

    On lim f(x)g(x)

    • 摘要: 构想借助函数代换的方式,对形如“limf(x)g(x)”的一种情形进行讨论.为此给出了两个命题及其证明,并举例讲述代换法的使用。

       

      Abstract: limf(x)g(x) is discussed here by means of function substitution. For it, two propositions and the proofs are given, and examples are taken to explain the use of substitution method.
