数学是高中教学课程里面的一个重要组成部分,数学成绩对高考总成绩有着一定的影响。其中,三角函数是非常重要的知识点,它在试卷里的分量是很大的,多种题型可以和三角函数的知识结合,选择题里有大概五分的比例,像其他填空题,解答题里面也有涉及,每隔一年的高考解答题第一道就是三角函数题,所以学好三角函数是很有必要的。如何更好的学习是需要方法的,学习三角函数可以从公式、图像、性质以及习题总结等方面进行,数学这门学科是离不开公式的,所以用公式解题是很常见的,但又不仅是简单的套公式,除了要把公式背好,更要理解公式中每个字母、每个符号所代表的含义,才有可能在解题的时候更快更好的解决问题。理解三角函数的图像和性质是解题必须的,对图像和性质不理解,学习和应用根本谈不上,所以必须下苦功学好记好每个函数的图像和性质。解题方法总结是一个全面实用的方法,不论哪个学科,总结题型及其相应的解法是行之有效的,这样在考试的时候可以更熟悉,更快的解答出来。本文针对这几种解题方法进行具体的分析。
Mathematics is a high school teaching curriculum which is an important part of mathematics results on the college entrance examination total score has a certain impact. Among them, the trigonometric function is a very important point of knowledge, it is in the test paper is a great component, a variety of questions and trigonometric functions can be combined knowledge, the choice of questions about the proportion of five, like other blank fill questions, answers The problem is also involved, every other year college entrance examination answer the first question is the trigonometric function, so learn trigonometry is necessary. How to learn better is a necessary method. The study of trigonometric functions can be carried out from the aspects of formulas, images, properties and exercises. The discipline of mathematics is inseparable from the formula. Therefore, it is very common to solve problems with formulas. However, Not only a simple set of formulas, in addition to formulating a good back, but also to understand each letter in the formula, each symbol represents the meaning, it is possible to solve problems faster and better solve the problem. Understand the trigonometric function of the image and the nature of the problem is necessary to solve the image and nature do not understand, simply do not learn and application, so you must hard work well remember the image and the nature of each function. Summary of the problem-solving method is a comprehensive and practical method, no matter which discipline, summarizes the type and its corresponding solution is effective, so that when the exam can be more familiar and faster answer. In this paper, these problem solving methods for specific analysis.
