高中平面三角里的“反三角函数”一章,是在高中三年级第一学期将近终了的时候教学的。现在我想对于怎样教学这一章,提出一些个人的意见。因为限于水平,这些意见难免有很多不妥和错误之处,希望读者批评指教。
The “anti-trigonometric function” chapter in the high school plane triangle is taught at the end of the first semester of the third year of senior high school. Now I want to put forward some personal opinions on how to teach this chapter. Because of the limited level, these opinions will inevitably have a lot of mistakes and mistakes. I hope the readers will criticize and advise.
