导数是微积分的初步知识,是研究函数、解决实际问题的有力工具,是高中数学知识的一个重要的交汇点,命题范围非常广泛.近年来高考数学试题既有利用导数研究函数的单调性、极值等有关性质的传统、常规问题,又有导数与集合、数列、三角函数、不等式的证明、线性规划、解析几何等的综合应用.解题既融合了转化与化归、分类讨论、函数与方程、数形结合等数学思想与方法,又注意了高考的重点
Derivatives are the initial knowledge of calculus, which is a powerful tool to study the function and solve practical problems. It is an important meeting point of mathematics knowledge in high school. The range of the proposition is very wide. In recent years, the mathematics test of entrance examines the monotonicity of functions, Extremum and other related properties of the traditional and routine problems, there are derivatives and sets, sequences, trigonometric functions, inequalities of proof, linear programming, analytic geometry, etc. The problem solving combines both transformation and transformation, classification, function And equations, mathematical combination of mathematical ideas and methods, but also pay attention to the focus of the college entrance examination
