导数是新教材增加的内容,又是学习高等数学的基础,所以在高考中占有重要的地位.高考对导数的考查定位于作为解决初等数学问题的工具出现,用导数研究函数的性质比用初等方法研究要方便得多,下面结合学生在导数的实际应用过程中常出现的一些典型错误,作一剖析以给读者前车之鉴. The derivative is the content of the new textbook, and it is the basis for learning advanced mathematics. So it occupies an important position in the college entrance examination. The examination of the derivative of the college entrance examination is positioned as a tool for solving elementary mathematics problems, and the nature of the function is studied with derivatives rather than with the elementary class. The method research is much more convenient. The following section will combine students’ typical mistakes that often appear in the practical application of derivatives, and make an analysis to give the reader a lesson.
