三角函数内容是高中数学中一个重要内容,在历年高考中,一份试卷一般有1道客观题,1道解答题,分值均占全卷总分的11.3%,难度要求一般是中等偏易。在历年高考中,三角函数重点考查的知识点有:与三角函数的性质有关问题(如单调性、奇偶性、周期性、极值点、对称性);与三角函数图象有关问题;与简单三角变换有关的问题(如三角求值、化简等);与解三角形有关 Triangle function content is an important part of high school mathematics, college entrance examination in the calendar year, a paper generally have 1 objective questions, 1 answer questions, the scores are accounted for 11.3% of the total score, the difficulty is generally required to moderate easy . In the college entrance examination over the years, the key points of the trigonometric function test are: problems related to the nature of trigonometric functions (such as monotonicity, parity, periodicity, extreme point, symmetry); problems related to trigonometric functions; Triangular transformation related issues (such as triangulation, simplification, etc.); and the triangle solution
