本文从一道数学题出发,结合一线教学实践经验,从不同的角度出发,采有不同的解题方法,讲三角函数于其他知识点相互交汇,从侧面地进行探究,这样不仅能使学生在解题上获得有效的解题思路,更重要的是培养学生的发散思维,是学生的思维得到极大地发散。 Starting from a math problem, combined with the practical teaching experience of first-line teaching, from different perspectives, we adopt different ways of solving problems, talk about the intersection of trigonometric functions with other knowledge points, and explore from the side, Questions to obtain effective problem solving ideas, more importantly, to develop students' divergent thinking, is the student's thinking has been greatly divergent.
