三角函数公式大全表(三角函数计算方法及快速查找表)
三角函数的关系
(正弦)Sin =对边A/斜边c
(余弦)Cos =邻边B/斜边c
(正切)Tan =对边A/邻边b
三角函数计算方法和快速查找表，做机械真的很有用。对边A =斜边C * Sin
对边A =邻边B * Tan
邻边B =斜边C * Cos
邻边B =对边A/Tan
C =对面A/Sin
斜边C =邻边B/Cos
例:给定斜边C = 20，角=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
=谭-((德-德)/ 2L)
这里给你提供sin，cos，tan不同角度的表值，准确度也很高。相信对你有用。
