高中物理新课标中“应用数学工具处理物理问题的能力”是高中物理教学的重要内容,也是高考物理能力考查的重点.数学中的正切函数反映了直角三角形中边与角之间的关系,在高中物理中,有关物理量之间的关系往往构成直角三角形,运用正切函数可使相关物理问题迎刃而解.本文通过几个实例来说明正切函数在高中物理解题中的重要地位以及巧妙应用.一、正切函数在物体平衡问题中的应用
High school physics in the new curriculum “The application of mathematical tools to deal with physical problems ” is an important part of high school physics teaching, but also the focus of physical ability test.Mathematical tangent function reflects the right triangle between the edge and the corner Relation, in high school physics, the relationship between the physical quantities often form a right triangle, the use of tangent function can solve the related physical problems solved.This paper illustrates the importance of tangent function in high school physics problem solving and clever application through several examples. First, the tangent function in the balance of objects in the application
