从八年级开始同学们就要学习初中数学中的一个重要知识——函数.函数是初中数学的重要组成部分,它深刻地反映了客观世界的运动和实际的量之间的依赖关系,如速度与时间,利润与售价、成本,通过坐标系中曲线上点的坐标反映对应关系.函数图像将函数的数量关系直观化、形象化,提供利用数形结合研究问题的重要方法.函数是揭示事物变化规律的有效手段,是研究运动变化的数学模型.那么我们又如何来学好这个重要的内容,使我们在数学思维上来一次飞
Since the eighth grade students have to learn an important knowledge in junior high school mathematics function - an important part of junior high school mathematics, which profoundly reflects the dependence of the objective world movement and the actual amount, such as speed And the time, profit and selling price, cost, through the coordinates of the coordinates of the points on the curve reflects the correspondence between the function of the number of the relationship between the visual function of the visualization, visualization provides the use of combination of mathematical methods to study the important methods. The function is to reveal An effective means of changing the law of things is to study the mathematical model of the change of movement.How we learn how to learn this important content so that we can fly in a mathematical way
