运动与变化是数学之精髓,更是数学之美的集中体现,以图像的形式刻画运动与变化是人们对美的追求与表现.将点的运动与其对应的函数图像相结合的试题,以多姿多彩的形式、新颖别致的内容,构成了数学试题中一道亮丽的风景.在体现数学外在“形式美”的同时,也体现了数学在思维方式上的“内在美”.在近几年的中考试题中,考查动点生成函数图像问题逐渐成为一种趋势.这类问题通过点、线或图形的运动构成一种函数
Movement and change are the essence of mathematics, but also the concentrated manifestation of the beauty of mathematics, depicting the movement and change in the form of images is the pursuit and performance of people for beauty.With the combination of point motion and its corresponding function image, In the form of novel and chic content, constitutes a beautiful test in a beautiful landscape in the expression of mathematics “form beauty ” at the same time, also reflects the mathematics in the way of thinking "inner beauty A few years of middle school exam questions, examining the problem of moving point generation function images gradually become a trend of these types of problems through points, lines or graphics to form a function of the movement
