设计圆面积公式推导的课件有很多软件,譬如flash、ppt等,但设计的课件主要有三点不足:效率不高、缺失数学味、互动性弱。本课件将填以往之缺失,基于数学原理尝试推出两种操作简便、效果优化的方法:函数思想方法和解析几何方法。下面是具体设计过程。一、方法一的设计过程 There are many softwares for the courseware such as flash, ppt, etc., which are derived from the design of the area formula. However, the design of the courseware mainly has three shortcomings: low efficiency, lack of mathematical taste and weak interaction. This courseware will fill in the shortcomings of the past, based on the principle of mathematics to try to introduce two simple and effective methods of optimization: function method and analytic geometry method. The following is a specific design process. First, the design of a method
