三角函数中的“三变”指的是“变角、变次、变姓”.文章对有关典型高考试题进行剖析和解答,引导解题者用心来体验、感悟一些所谓的“高超技巧”是如何实现“熟路驾轻车,别扭变自然”的.文章从对三种变形的分析中还指出解题者应优化解题心态,尤其是要达到良好心理状态,在积累经验的基础上提升自己,树立先进的解题理念.这些对于学生从根本上提高数学学习水平、增强解决问题的能力、优化数学素养都具有非凡的意义.
The “trivariate” in the trigonometric function refers to “changing angle, changing times, and changing surname”. The article analyzes and answers questions concerning typical high test questions, and guides the problem solver to experience and comprehend some so-called “Superb skills” is how to achieve “a good road, do not twist nature,” the article from the analysis of the three kinds of deformation also pointed out that the problem solver should optimize the problem-solving mentality, especially to achieve a good psychological state, On the basis of accumulating experience, we must improve ourselves and establish advanced problem-solving concepts. These are of great significance for students to fundamentally improve the level of mathematics learning, enhance the ability to solve problems, and optimize mathematical literacy.
