三角函数值是 三角函数计算方法及快速查询表

三角函数值(三角函数计算方法和快速查找表)

三角函数关系

(正弦)正弦=对边α/斜边β

(余弦)Cos =邻边B/斜边c

(正切)Tan =相对侧A/相邻侧b

对边A =斜边C * Sin

相对侧A =相邻侧B * Tan

邻边B =斜边C * Cos

相邻侧B =相对侧A/Tan

斜面C =反面A/Sin

倾斜侧C =相邻侧B/Cos

例:已知斜边C=20，角度=35度，求对边a和邻边b。

对边A =斜边c * sin = 20 * sin(35)= 20 * 0.573576 = 11.471

邻边B =斜边c * cos = 20 * cos(35)= 20 * 0.81915 = 16.383

普通车床锥度与三角函数的关系

锥度比T=(大直径D-小直径d)/(长度l)

Tan=(大直径D-小直径d)/(2*长度l)

D= d 2*L* Tan

d= D - 2*L* Tan

= Tan - ( (D-d) / 2L)

这里我们从不同角度给大家提供sin、cos、tan的表值，准确度也很高。我相信它对你有用
