三角函数是基本初等函数之一,是学生在高中阶段学习的又一类重要的基本初等函数,在高中数学教材中占有非常重要的地位,是每年高考必考的六大重点内容之一,也是高考的热点之一。从近几年的高考看,三角函数在高考中常以两道小题,一道大题的形式出现,题型和分值的分布主要是选择或填空题1~2个,解答题1个,大致17~22分,难度中低档,而且由于它的位置往往在解答题第1~2题,对中低层次的学生来说,后两个大题只能得一
Trigonometric function is one of the basic elementary functions, and it is another important basic elementary function that students study in high school. They occupy a very important position in high school mathematics textbooks and are also one of the six key points in the annual college entrance examination. One of the hot spots in college entrance examination. From the college entrance examination in recent years, the trigonometric functions in college entrance examination often two small questions, a big problem in the form of questions and score distribution is mainly to select or fill in the blank questions 1 to 2 answer questions 1, roughly 17 to 22 minutes, the degree of difficulty in low-grade, and because of its location is often in the answer questions 1 to 2 questions, to the low-level students, the latter two big problems can only get one
