论文部分内容阅读
一、主要内容: ①反三角函数的性质:定义域、值域、奇偶性、单调性、图象及简单的运算公式等。 ②求最简单的三角方程的解集方法,可转化的简单三角方程的解法。 根据近几年高考形势,特别是实行“3+2”考试制度后的情况分析,本章内容基本上遵循下列特点。 (一)命题有“三不变”,即命题方式不变,命题范围不变,命题目的不变。 本章命题形式主要是客观题,即每年仅出1～2道选择题或填空题,题目考查的知识点也以课本内容为主,其中突出考查反三角函数(特别是反正弦函数和反余弦函数)的基本性质。简单的三角方程的解法也在考试之列。命题的目的仍然是考查考生基本知识掌握情况和基本的解题技能。
First, the main content: 1 The nature of the inverse trigonometric function: the definition of the domain, value domain, parity, monotony, images and simple calculation formulas. 2 Find the solution set method of the simplest trigonometric equation, the solution of the simple trigonometric equation that can be transformed. According to the situation of the college entrance examination in recent years, especially after the implementation of the “3+2” examination system, the contents of this chapter basically follow the following characteristics. (1) The proposition has “three invariables”, that is, the propositional method remains unchanged, the scope of the proposition is unchanged, and the subject’s invariance remains unchanged. The proposition form in this chapter is mainly an objective question, that is, there are only 1 to 2 multiple-choice questions or fill in blank questions each year. The knowledge points of the topic examination are also mainly textbook contents, among which the anti-trigonometric functions are highlighted (especially the inverse sine function and the inverse cosine function. The basic nature of The simple solution of the trigonometric equation is also included in the exam. The purpose of the proposition is still to examine candidates’ basic knowledge and basic problem-solving skills.
