高级中学课本平面三角是在初中代数已经学过了函数的概念,初中几何已经学过了三角函数的定义、直角三角形的解法和一部分斜三角形的解法的基础上来编写的。用这本课本进行教学的要求是:使学生掌握有关三角函数、反三角函数的一些概念和性质,能够作出它们的图象;掌握有关三角函数的一些重要公式,能够熟练地进行三角函数的恒等变形和正确地解三角方程;能够熟练地根据公式应用对数解三角形。
High school textbook plane triangulation is in the junior high school algebra has learned the concept of function, junior geometry has learned the definition of trigonometric functions, right triangle and part of the oblique triangle triangle solution based on the solution. The requirement of teaching with this textbook is to enable students to master some concepts and properties of trigonometric and inverse trigonometrical functions and to be able to make their images. To master some important formulas concerning trigonometric functions, Deform and properly solve the trigonometric equations; Apply logarithmically resolved triangles to formulas.
