导数(Derivative)是微积分中的重要基础概念,涵盖了函数、几何、不等式等相关领域,是高中数学的必修内容,也是高等数学的基础。由于高中教学在导数方面仅侧重于基本概念和简单运用,课时偏少,因此成为许多同学的薄弱环节。本文结合作者自己的复习体会,尝试理清导数的基本概念、常用公式,并通过实战练习帮助同学们在“导数及其应用”复习时,触类旁通、举一反三,提高复习效果。 Derivative is an important basic concept in calculus. It covers functions, geometries, inequalities and other related fields. It is a compulsory part of high school mathematics and a foundation of advanced mathematics. Because high school teaching only focuses on the basic concepts and the simple application of derivative in terms of derivative, it has become the weak link of many students. Based on the reviewing experience of the author, this article tries to clarify the basic concepts and formulas of the derivative, and help the students through the practical exercises to bypass the analogy and improve the reviewing effect when the “derivative and its application” are reviewed.
