摘要
分析了函数极限的重要性,用函数极限的定义证明lim x→x0f(x)=a,用函数极限定义的否定形式证明:当lim x→x0f(x)≠a及x→x0时,f(x)发散。
The importance of the limit of the function is analyzed. By using the definition of the limit of the function, how to prove that lim x→x0f（x）=a is given. By using the negativity of the definition of the limit of the function, how to prove that lim x→x0f（x）≠a andf（x） is divergent as x→x0 are also given.
