sin36°用根号表示 sin75度等于多少啊

睿知生活知识

今天小编为大家整理了函数的计算方法，应该对从事数控行业的你有所帮助 。如果不会，那就赶紧学 。
角度关系
(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
C =相对侧A/Sinθ
C =邻边B/Cosθ
例:给定斜边C = 20，角θ=35度，求对边A和邻边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=(大直径D-小直径d)/(长度L)
Tanθ=(大直径D-小直径d)/(2*长度L)
D= d 2*L* Tanθ
【sin36°用根号表示 sin75度等于多少啊】d= D - 2*L* Tanθ
θ= Tan - ( (D-d) / 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 。
