导数的性质及其应用是高考的一个热点,从近几年高考来看,各省市的高考题涉及到导数的知识或内容的题目一般在20分左右,约占12%.导数部分主要考查利用导数求曲线切线、利用导数研究函数性质(包含单调性、最值、图象、根等)、利用导数证明不等式以及导数的实际应用问题等.特别是利用导数求函数的单调区间与最值为必考的内容之 The nature of the derivative and its application is a hot spot for the college entrance examination, college entrance examination in recent years, the provincial college entrance examination questions related to the subject of knowledge or content of the derivative is generally about 20 points, accounting for about 12% Derivative of the tangent curve, the use of derivatives to study the nature of the function (including monotonicity, the most value, image, root, etc.), the use of derivatives to prove the inequality and the practical application of derivatives, etc. Especially the use of derivatives of the monotonic interval function and the value of The content of the exam
