根据总路綫的精神,我們提前結束了高中一年級的数学課以后,根据我們自编的过渡性数学教学大綱草案,吸取了黑山教学改革的經驗,进行了三角教学改革的試驗,取得了良好的效果。在試驗中我們进一步体会到只要认真体会黑山經驗的精神实质,結合学生实际,結合教学內容、特点,黑山小学的經驗是可以成功地运用于中学的。我們把三角的全部內容分为五节: 1.三角函数。以三角函数的坐标定义为基础,系統地研究同角各三角函数間的关系,特殊角三角函数,三角函数的符号和誘导公式。 2.加法定理。以和角的正弦、余弦的公式为基
In accordance with the spirit of the general line, after we ended early mathematics classes in the first year of high school, according to the draft of the transitional mathematics syllabus compiled by us, we learned the experience of teaching reform in Montenegro and conducted experiments on the reform of the teaching of the triangle. We achieved good results. effect. In the experiment, we further realized that as long as we seriously understand the spiritual essence of the experience of Montenegro, combined with the actual situation of the students, combined with the teaching content and characteristics, the experience of the Montenegrin Elementary School can be successfully applied to the middle school. We divide the entire contents of the triangle into five sections: 1. Trigonometric functions. Based on the definition of the coordinates of the trigonometric function, the relations among the trigonometric functions of the same angle, the special angle trigonometric function, the sign of the trigonometric function and the induction formula are systematically studied. 2. Addition Theorem. Based on the sine and cosine formulas of angles
