利用运动相对性解题３１１３１１浙江临安於潜中学叶芳琴我们知道，运动和静止是相对的．当对象Ａ相对于静止的对象Ｂ运动时，也可视为对象Ｂ相对于静止的对象Ａ运动．运动的这种相对性，在数学解题中有化繁为简、化难为易的作用．现举例如下．例１直角三角形ＡＢＣ中，Ｃ... Use of motion relativity solution problems 311 311 Zhejiang Linan Yu Qian Middle School Ye Fangqin We know that motion and stillness are relative. When the object A is moving relative to the stationary object B, it can also be regarded as the object B moving relative to the stationary object A. This relativity of the movement, in the mathematics problem solving, has the effect of simplifying and simplifying and making things difficult. The example is as follows. Example 1 right triangle ABC, C...
