新课程标准重视培养同学们运用数学知识分析和解决实际问题的能力,因此近年来各地中考试题中频频出现具有时代气息的应用题.通过把实际问题抽象成数学问题,再运用数学知识加以解决,使同学们进一步理解数学的应用价值.现就二次函数的应用性问题,精选两例解析如下,供同学们参考.例1(2010年山东潍坊)学校计划用地面砖铺设教学楼前矩形广场的地面ABCD,已
The new curriculum standards focus on training students ability to use mathematical knowledge to analyze and solve practical problems, so in recent years the test questions in various places frequently appear with the flavor of the times the application of the problem.By abstracting the actual problems into mathematical problems, and then use mathematical knowledge to be solved, So that students can further understand the application of mathematics value.Now on the application of quadratic function problems, the selection of two cases as follows, for the students to refer to.Example 1 (Weifang, Shandong Province) school plans to use the floor tiles in front of teaching building rectangular square The ground ABCD, already
