历年中考都有相当一部分学生将很容易得分的题做错了,或解答不完整.考察原因,一是对基本概念掌握不准确,二是思考问题不严谨周密.本文以近几年中考题为例,谈谈函数与几何中最常见的易犯错误,在中考前给同学们提个醒.一、函数及其图象方面的易错题例1在平面直角坐标系xOy中,已知A(2,-2),在y轴上确定点P,使△AOP为等腰三角形,则符合条
Many of the senior high school entrance examinations over the years have made it easy for students to score questions incorrectly or incompletely. To investigate the reasons, one is to master the basic concepts inaccurately, and the other is to think that questions are not rigorous. This article uses the exam questions in recent years as an example. , to talk about the most common mistakes in functions and geometry, to remind the students before the middle of the exam. First, the function and the image of the error-prone cases 1 in the plane rectangular coordinate system xOy, known A (2,-2), determine the point P on the y-axis so that △AOP is an isosceles triangle
