随着高考的不断改革,高考试题中的三角函数变化不大,遵循与前一年基本不重复,高考试题中的三角函数出现在第一题,题相对比较传统,难度较低,位置合理,每年必考。因此,在复习过程中既要注重三角知识的基础性,突出三角函数的图象、周期性、单调性、奇偶性、对称性等性质以及化简、求值和最值等重点内容的复习,又要注重三角知识的工具性,突出三角与代数、几何、向量的综合联系,以及三角知识的应用意识。下面分别是2013年与2014年
With the continuous reform of college entrance examination, the trigonometric function in the entrance examination questions has little change, follow the basic non-repetition with the previous year, the trigonometric functions in the entrance examination questions appear in the first question, the question is relatively traditional, the difficulty is low, the location is reasonable, Every year will test. Therefore, it is necessary to pay attention to the basic knowledge of trigonometry in the reviewing process, highlight the properties of trigonometric functions such as image, periodicity, monotonicity, parity, symmetry, review of the key contents such as simplification, At the same time, we should pay attention to the instrumentalities of trigonometry knowledge, highlight the comprehensive relations between triangles and algebra, geometry and vector, as well as the awareness of the application of trigonometry knowledge. The following are 2013 and 2014 respectively
