近几年来,高考对三角函数部分的考查一般是先进行三角恒等变换,再利用三角函数的图像与性质解题,这既较全面地考查三角函数这部分知识内容,又达到考查考生演绎推理能力的目的.三角函数题目本身就是破解这道题的信息源,所以考生在审题时一定要逐字逐句看清楚.只有细致地审题,考生才能从题目本身获得尽可能多的信息.找到解题方法后,书写要简明扼要,快速规范,不拖泥带水,牢
In recent years, college entrance examination on the part of the trigonometric function is generally the first triangle constant transformation, and then use the trigonometric function of the image and the nature of the problem-solving, which not only more comprehensive examination of trigonometric functions of this part of the knowledge content, but also to examine the candidate deductive reasoning The purpose of the function of the trigonometric function itself is the source of information to solve this problem, so candidates in the exam must be verbatim by sentence to see clearly only carefully meticulous examination, candidates can get as much information from the subject itself as possible. , Writing should be concise, fast norms, not dragons, jail
