数学是教学体系的重点与难点课程,其主要考察学生的抽象思维与逻辑思维,是数学学习的关键方式。数形结合思想是数学领域中一种独特的解题方法,主要是利用专业的数学语言和几何图形来相互结合,能将知识点立体化、具体化,便于学生对知识点的理解与把握。通常情况下,数形结合思想主要应用到三角函数知识点方面,应用效果理想。为此,本文就数形结合思想在三角函数中的应用进行了分析与探究。
Mathematics is the key and difficult course of the teaching system. Its main consideration is the abstract thinking and logical thinking of students, which is the key way of learning mathematics. The idea of combination of number and shape is a unique method of solving problems in the field of mathematics. It mainly uses specialized mathematical language and geometry to combine with each other, which can make the knowledge points three-dimensional and specific, which is convenient for students to understand and grasp the knowledge points. Under normal circumstances, the combination of the number theory mainly applied to trigonometric function knowledge point, the application effect is ideal. For this reason, this paper analyzes and probes into the application of the combination of number and shape in trigonometric functions.
