导数是研究函数的工具,导数的引入拓展了函数的命题空间,拓宽了函数问题解决的思路,优化和丰富了解题的方法和技巧,大大提高了我们运用数学思想方法去分析、解决数学问题与实际问题的能力.下面就利用导数解决函数单调性、极值、最值、切线、方程的根、参数等进行分析、归纳、总结,供同学们参考。 Derivatives are tools for studying functions. The introduction of derivatives expands the proposition space of functions, broadens the ideas for solving function problems, optimizes and enriches methods and techniques for understanding problems, and greatly improves the use of mathematical thinking methods to analyze and solve mathematical problems. With the ability of practical problems. The following uses the derivative to solve the monotony of the function, the extreme value, the most value, tangent, the root of the equation, parameters, etc. are analyzed, summarized and summarized for reference by the students.
