导数作为一种工具,在解决数学问题时应用极为方便,尤其是利用导数可以求函数的单调性、极值、最值以及曲线的切线,但学生由于对基本概念、基本理论理解不准确而导致失误屡见不鲜.本文对导数应用中常见的一些错误作一简要剖析,供大家参考. Derivatives, as a tool, are extremely convenient for solving mathematical problems. In particular, derivatives can be used to find the monotonicity, extreme value, and maximum value of a function, as well as the tangent of the curve. However, students are not able to understand basic concepts and basic theory because of their inaccurate understanding. Errors are not uncommon. This article gives a brief analysis of some common mistakes in derivative applications for your reference.
