一、问题提出数学题目千变万化,常见运动问题分为图形的三种运动和动点问题.数学中的动点问题是指在题干中存在一个或多个动点,这些点在线段、射线或弧线上运动的开放性题目.解决这类问题的关键是首先弄懂题干,理清题意,使题目中的图像同步动起来,从动至静,以静制动,再找出临界点,将动点问题中的“变”与“不变”融为一体,灵活运用相关数学知识解决问题.二、内容分析纵观各地历年以来的单圆背景下的动点问题,基本都是以圆作为研究背景,从变换的角度和运动变化来分析三角形、四边形、函数图像等图形,通过“对称、
First, the problem put forward the ever-changing mathematical problems, the common problem of movement is divided into three graphical motion and moving point problem. The problem of moving point in mathematics is that there are one or more moving points in the stem, these points in the line, ray or The key to solve this kind of problem is to first understand the problem, clarify the problem, make the images in the topic move synchronously, move from the static to the static, the static braking, and then find the critical Point, the question of moving point ”change “ and ”immutable “ blend, flexible use of relevant mathematical knowledge to solve the problem.Second, content analysis Throughout the years over the single-circular background of the moving point problem , Are basically round as a research background, from the transformation point of view and movement changes to analyze the triangle, quadrilateral, function images and other graphics, through the ”symmetry,
