摘　　要：利用导数基本公式及运算法则进行导数运算是很普遍的,而导数定义在求分段函数、某点导数及抽象函数求导等运算中有着独特的作用。结合例题对导数定义在运算中的应用进行探讨,对教学有一定的启发性。Using the basic formula and algorithms of derivative for its calculation is very common.However,the definition of derivative has a unique role,particularly in solving the derivative of section function,certain point derivative and abstract function etc.The application of the derivative definition in calculation combined with examples is discussed in this paper,which is heuristic for teaching process.
