连续是高等数学教学中基本概念之一 ,它是可导(可微 )、可级等概念的基础 ,没有连续 ,就谈不上可微和可级。因此 ,准确掌握连续概念 ,是学好高等数学的关键。现就教学过程常见的几个问题讨论如下 :一、函数在某点连续的概念函数 f(x)在已知点 x连续有多种定义方法 ,它们是彼此 Continuity is one of the basic concepts in advanced mathematics teaching. It is the basis of the concepts of differentiable, differentiable, and scalable. Without continuity, it is impossible to tell the difference. Therefore, accurately grasp the concept of continuous, is the key to learning advanced mathematics. Now on the teaching of several common problems discussed as follows: First, the function of a continuous point at a certain point Function f (x) There are a variety of continuous definition of the known point x method, they are each other
