角函数的关系
(正弦) sin θ = 对边A / 斜边C
(余弦) Cosθ = 邻边B / 斜边C
(正切) Tanθ = 对边A / 邻边B
对边A = 斜边C * Sinθ
对边A = 邻边B * Tanθ
邻边B = 斜边C * Cosθ
邻边B = 对边A / Tanθ
斜边C = 对边A / Sinθ
斜边C = 邻边B / Cosθ
例题：已知斜边C=20, 角度θ=35度求对边A及邻边B
对边A =斜边C * Sinθ= 20 * Sin (35) = 20 * 0.573576 = 11.471
邻边B =斜边C * Cosθ= 20 * Cos (35) = 20 * 0.81915 = 16.383
一般车床锥度与三角函数的关系锥度比T=(大径D-小径d) / (长度L)
Tanθ= (大径D-小径d) / (2*长度L )
D= d 2*L* Tanθ
d= D - 2*L* Tanθ
θ= Tan - ( (D-d) / 2L )
这里为你提供了sin,cos,tan不同角度的表值，精确度也很高了，相信对你有用
