反比例函数是中考的一个热点函数,以它为载体的中考题简洁明了,而考查的数学知识点、数学思想方法不简单.利用双曲线的对称性、k的几何意义是解决问题的关键,在2014的中考中,出现一类以架构在双曲线上的多边形的中考题,这类试题考查函数、方程、勾股定理、三角形、特殊的四边形等知识点,以及待定系数法、数形结合、分类讨论、方程、函数
The inverse proportion function is a hot spot function of the senior high school entrance examination, the middle school entrance examination question which takes it as the carrier is concise and clear, and the mathematical knowledge points and mathematics thinking method that examine examines are not simple.Using the hyperbolic symmetry, the geometric significance of k is the key to solving the problem In the middle school entrance examination in 2014, there appeared a type of middle school entrance examination questions on polygons with hyperbolic structure. Such examination questions such as function, equation, pythagorean theorem, triangle, special quadrilateral and other knowledge points, as well as undetermined coefficient method, Category Discussion, Equation, Function
