New Teaching Method of Limits of the Basic Elementary Functions

XIE Shunqiang;Beijing Vocational College of Labor and Social Security;  
The limit of basic elementary function is an important part of calculus teaching.However,because of the general poor mathematical foundation of the students in higher vocational colleges,this brings a great challenge to the teaching.The article puts forward a new idea to teach the limits of basic elementary functions.Firstly,the limit concept is given a preliminary instruction based on the power function.Secondly,the thinking method of limits of the basic elementary functions is given,and the limits of the exponential function,trigonometric function,logarithmic function and inverse trigonometric function are given respectively.Finally,a summary of limits of the basic elementary functions is given.
