数形结合是求解高中数学问题的一种重要而实用的思想方法,即根据数形之间的对应关系,将抽象的数学语言与直观的几何图形联系起来.数形结合的思想广泛应用于高中数学各个方面.本文将列举其在三角函数、不等式和解析几何中的应用,为学生的学习提供借鉴.
The combination of number and shape is an important and practical thought method for solving high school mathematics problems. It is based on the correspondence between numbers and shapes, and relates abstract mathematics language to intuitive geometric figures. The idea of number and shape combination is widely used in high school. Various aspects of mathematics. This article will list its applications in trigonometric functions, inequalities, and analytic geometry to provide lessons for students’ learning.
