从《数学课程标准》看，中学数学把三角学内容分成两个部分，第一部分放在义务教育第三学段，第二部分放在高中阶段。

在义务教育第三学段，主要研究锐角三角函数和解直角三角形的内容，本套教科书安排了一章的内容，就是本章“锐角三角函数”。

在高中阶段的三角内容是三角学的主体部分，包括解斜三角形、三角函数、反三角函数和简单的三角方程。

无论是从内容上看，还是从思考问题的方法上看，前一部分都是后一部分的重要基础，掌握锐角三角函数的概念和解直角三角形的方法，是学习三角函数和解斜三角形的重要准备。

常用三角函数值对照表及表示度数三角函数是数学中重要的概念，在解决几何问题和物理问题中有着广泛应用。

常见的三角函数包括正弦函数、余弦函数和正切函数。

这些函数在不同的角度下具有不同的数值，下面将介绍它们在特定角度下的取值，并给出一个简单的对照表。

正弦函数正弦函数通常记作sin，表示一个角的对边与斜边的比值。

在不同角度下，正弦函数的取值如下：•sin(0°) = 0•sin(30°) = 1/2•sin(45°) = √2/2•sin(60°) = √3/2•sin(90°) = 1余弦函数余弦函数通常记作cos，表示一个角的邻边与斜边的比值。

在不同角度下，余弦函数的取值如下：•cos(0°) = 1•cos(30°) = √3/2•cos(45°) = √2/2•cos(60°) = 1/2•cos(90°) = 0正切函数正切函数通常记作tan，表示正弦和余弦的比值。

正弦、余弦和正切值表在很多数学函数中都有重要作用，其中三角函数及其应用就十分常见。

正弦余弦正切值表又称三角函数值表，下面将对这三个值进行分别介绍：1. 正弦值：正弦值就是指一个角度的弧度值，在高中一般是指一个输入角度并固定返回正弦值。

正弦值表中最常用的值就是 0、π/2、π/6、π/3和2π/3，其正弦值分别为0、1、1/2、sinπ/6=√3/2 和sin2π/3=-√3/2。

2. 余弦值：余弦值也是指一个角度的弧度值，但其计算方式和正弦值有所不同。

余弦值表中最常用的值就是 0、π/2、π/3 和3π/4，其余弦值分别为1、0、√3/2 和cos3π/4=-1/2。

特殊角度的三角函数值对照表特殊角度三角函数值对照表是数学中的一个工具，它帮助我们快速计算特殊角度的正弦、余弦和正切值。

特殊角度是指能够被简化为一个特定比值的角度，例如30°、45°、60°等。

这些特殊的角度在几何和三角函数的计算中经常出现，所以熟悉它们的三角函数值是很有用的。

在特殊角度三角函数值对照表中，通常包括角度的度数和弧度两种表示方法，以及对应的正弦、余弦和正切值。

下面是一个1200字以上的特殊角度三角函数值对照表。

这是因为在单位圆上，角度为0度时，对应的终边在横轴上。

而在特殊角度30度、45度和60度对应的正弦、余弦和正切值是根据三角函数的定义和三角恒等式计算得出的。

例如，当角度为30度时，它的正弦值为1/2，余弦值为√3/2，正切值为1/√3、这是因为在单位圆上，角度为30度时，对应的终边与x轴正向和y轴正向的夹角都是30度，所以正弦值为终边的y坐标除以半径，即1/2；余弦值为终边的x坐标除以半径，即√3/2；正切值为终边的y坐标除以终边的x坐标，即1/√3类似地，当角度为45度时，它的正弦值和余弦值都是1/√2，正切值是1、这是因为在单位圆上，角度为45度时，对应的终边与x轴正向和y轴正向的夹角都是45度，所以正弦值和余弦值都是终边的y坐标和x坐标除以半径的比，即1/√2；正切值是终边的y坐标和终边的x坐标的比，即1同样地，当角度为60度时，它的正弦值为√3/2，余弦值为1/2，正切值为√3、这是因为在单位圆上，角度为60度时，对应的终边与x轴正向和y轴正向的夹角都是60度，所以正弦值为终边的y坐标除以半径，即√3/2；余弦值为终边的x坐标除以半径，即1/2；正切值为终边的y 坐标除以终边的x坐标，即√3当角度为90度时，它的正弦值为1，余弦值为0，正切值不存在。
