三角函数是普通高中数学教学中的重、难点内容。每年在高考数学试卷中与三角函数相关的试题都占据很大比例。高中数学本身是极其抽象且难度较大的学科,而三角函数知识应用对于学生思维能力和推理运用能力更是一种考验。因此,高中数学教师要不断充实和完善教学内容及方法,针对高中三角函数知识规律和总结,进而有效地提高学生对三角函数知识应用的解题技能和技巧。
Trigonometric function is the heavy and difficult content in ordinary high school mathematics teaching. Each year in the college entrance examination mathematics papers and trigonometry-related questions account for a large proportion. High school math itself is extremely abstract and difficult subjects, and the application of trigonometric function knowledge for students thinking ability and reasoning ability is a test. Therefore, high school mathematics teachers should continue to enrich and improve the teaching content and methods, according to the high school trigonometric function rules of knowledge and summary, and thus effectively improve students’ knowledge of the application of trigonometric function solving skills and skills.
