在初中数学中,我们重点学习了一系列知识,本文分别对二次函数及其图象的画法,二元一次方程组的求解,以及三角形全等和相似的证明这三方面的知识进行了总结与学习,以期能帮助学生突破这些重点和难点,促进他们形成系统的学习方法。一、二元一次函数图象绘制学习想要学好初中数学函数,绘制函数图象是关键。画图象的关键还是对方程的基本元素的把握,有一定的基础之
In junior high school mathematics, we focus on learning a series of knowledge, this paper respectively on the quadratic function and its image method, the solution of the binary linear equations, and triangle equivalence and similar proof of these three aspects of knowledge Summarize and study, with a view to helping students to break through these key and difficult points, and promote their formation of systematic learning methods. First, the binary function of the image to draw Learn to learn good math functions, drawing function images is the key. The key to drawing images is still to grasp the basic elements of the equation, there is a certain basis
