贵刊今年第五期刊登赵明绩、王晓霞写的《求ｔａｎ15°值的几种方法》一文 ,介绍了四种用构造图形求ｔａｎ15°函数值的方法 .如文中所言 ,在数学学习中 ,经常进行这样的练习 ,有助于开发智力 ,培养学生的思维的灵活性 .笔者认为 ,这一类训练还有助于掌握数形结合的数学方法 . In the 5th issue of your magazine this year, Zhao Wenji and Wang Xiaoxia wrote “How to Solve tan15° Values.” This article describes four methods for finding function values ​​of tan15° using structural drawings. As the text states, in mathematics learning, often Conducting such exercises helps develop intelligence and fosters students’ flexibility of thinking. The author believes that this type of training also helps to grasp the mathematics method of combining numbers and shapes.
