所谓“新定义”型问题,主要是指在问题中定义了初中数学中没有学过的一些概念、新运算、新符号,要求同学们读懂题意并结合已有知识、能力进行理解,根据新定义进行运算、推理、迁移的一种题型.“新定义”型问题成为近年来中考数学新亮点.一、阅读理解中的新定义例1(2016年浙江湖州)定义:若点P(a,b)在函数y=1/x的图像上,将以a、b为系数构造的二次函数y=ax~2+bx称为函数y
The so-called “new definition ” type of question, mainly refers to the definition of the problem in junior high school mathematics did not learn some concepts, new computing, new symbols, require students to read the title and combined with existing knowledge and ability to understand , According to the new definition of computing, reasoning, migration of a type of problem. “New definition ” type problem becomes a new bright spot in mathematics test in recent years .A new definition in reading comprehension 1 (2016 Huzhou, Zhejiang) Definition: If the point P (a, b) is on the image of the function y = 1 / x, the quadratic function y = ax ~ 2 + bx constructed by a, b is a function y
