“三角函数”是具有特殊文化背景的数学分支,对这一章的教材的编写关键在于对其文化背景的认识与价值取向的定位.我们在编写苏教版教材时对此进行了充分的思考,并研究了国内、外很多教材中相应内容的处理方法.下面是我们在编写过程中形成的一些认识及经过近几年的实验后的一些反思.1对本章内容的分析与认识我们认真分析与研究了本章内容的整体结构、各部分的内在联系,特别是其形成与发展的历史过程.1.1锐角三角函数与任意角的三角函数之间的关系我们发现,相当部分的国内、外教材是以锐角三角函数进行推广,从而引入任意角的三角函数的,我
“Trigonometric function ” is a branch of mathematics with a special cultural background, and the key to composing this chapter is to know its cultural background and value orientation. , And studied the corresponding content processing methods in many textbooks at home and abroad.The following are some thoughts we formed in the process of compilation and some reflections after the experiments in recent years.1 Analysis and recognition of the contents of this chapter Carefully analyzed and studied the overall structure of this chapter, the internal links between the various parts, especially the historical process of its formation and development.1.1 The relationship between trigonometric trigonometric functions and trigonometric functions of any angle We found that a considerable part of the domestic and foreign Textbook is based on trigonometric trigonometry function to promote, thus introducing trigonometric functions of any angle, I
