完整初中三角函数值表~
完整初中三角函数值表如下图所示：
常见的三角函数包括正弦函数、余弦函数和正切函数。在航海学、测绘学、工程学等其他学科中，还会用到如余切函数、正割函数、余割函数、正矢函数、余矢函数、半正矢函数、半余矢函数等其他的三角函数。不同的三角函数之间的关系可以通过几何直观或者计算得出，称为三角恒等式。

起源
公元五世纪到十二世纪，印度数学家对三角学作出了较大的贡献。尽管当时三角学仍然还是天文学的一个计算工具，是一个附属品，但是三角学的内容却由于印度数学家的努力而大大的丰富了。
三角学中”正弦”和”余弦”的概念就是由印度数学家首先引进的，他们还造出了比托勒密更精确的正弦表。
我们已知道，托勒密和希帕克造出的弦表是圆的全弦表，它是把圆弧同弧所夹的弦对应起来的。印度数学家不同，他们把半弦（AC）与全弦所对弧的一半（AD）相对应，即将AC与∠AOC对应，这样，他们造出的就不再是”全弦表”，而是”正弦表”了。
印度人称连结弧（AB）的两端的弦（AB）为”吉瓦（jiba）”，是弓弦的意思；称AB的一半（AC） 为”阿尔哈吉瓦”。后来”吉瓦”这个词译成阿拉伯文时被误解为”弯曲”、”凹处”，阿拉伯语是 ”dschaib”。十二世纪，阿拉伯文被转译成拉丁文，这个字被意译成了”sinus”。
给你两个表，第一个是5°至360°每隔5°的角的正弦、余弦、正切、余切函数的高精度近似值。
第二个是0°、15°、18°、30°、36°、45°、54°、60°、72°、75°、90°这些角的正弦、余弦、正切函数精确值的数学表达式。其他角的三角函数精确值的数学表达式一般极其复杂，故未收录。90°以上角的三角函数可借助此表用诱导公式求出。
