新颁全日制高中《数学教学大纲》关于正弦定理、余弦定理有这样一段文字:掌握正弦定理、余弦定理,并能运用它们解斜三角形,能利用计算器解斜三角形的计算问题.大纲的要求可谓简单不过,但结合《高中数学课程标准》的“以问题为起点,以变式探究为重点,以培养创新意识为目标”的学 Newly awarded full-time high school mathematics teaching syllabus about sine theorem, cosine theorem has such a section of text: master sine theorem, cosine theorem, and can use them to solve oblique triangles, can use the calculator to solve oblique triangle calculation problems. outline requirements It can be said to be simple, but with the “high school mathematics curriculum standards,” the “question as a starting point, focus on variant inquiry, with the aim of cultivating innovative consciousness”
