论文部分内容阅读
在全日制十年制高中数学二册62页—63页谈到有关地球经纬问题。这点教材,难度较大,学生不易理解。我想就这个问题作一些探讨。
In the full-time 10-year high school mathematics book, pages 62-63, we talk about the problems of the Earth’s longitude and latitude. This textbook is more difficult and difficult for students to understand. I want to make some discussion on this issue.
