函数几何综合问题重点是考查学生灵活运用函数知识和几何知识解决数学综合题的能力.这类问题分两大类型:(1)几何元素间的函数关系问题,即根据已知几何图形的度量性质关系建立自变量与函数所表示的几何元素间的等量关系,求出函数关系式,运用函数工具解决几何图形中的问题;(2)函数图象中的几何图形问题,即根据已知函数图象中的几何图形的位置特征,运用数形结合方法解决有关函数、几何问题.解答此类问题,关键是熟悉各种函数图形的形状、性质和位置关系,正确地进行数和形的转换.本人分析
Function geometric synthesis problem focuses on the ability of students to use functional knowledge and geometric knowledge to solve mathematical comprehensive questions.This type of question is divided into two types: (1) the functional relationship between geometric elements, that is, according to the measured geometry of known geometry Relationship between the independent variables and the geometric elements represented by the function to determine the relationship between the function, the use of functional tools to solve the problem of geometry; (2) geometric images in the function of the problem, which is based on known functions To solve these problems, the key is to get acquainted with the shapes, properties and positional relationships of various function graphics and correctly convert the numbers and shapes I analyze
