sin85°等于多少
答:sin(85°) = 0.99619469809175 sin(90°) = 1
答:sin85°=sin95°=0.9962,只能查表,没有办法直接计算出来的。
答:斜坡的长度是36.1375米。sin85=0.99619斜坡=36÷sin85=36÷0.99619=36.1375 这是运用的三角函数的正弦值 ...

答:85π/180约等于1.48 即85度约等于1.48弧度 而0
答:sin85° = 0.996194698091746; cos85° = 0.0871557427476584;tan85° = 11.4300523027613; cot85° = 0.0874886635259242;sin90° = 1; cos90° = 0;tan90° = ∞; cot90° = 0;sin95° = 0.996194698091746; cos95° = -0.0871557427476582;tan95° = -11.4300523027613; cot95° = -0.0874886635259241;sin...

答:sin1.5>1,sin85度小于1. Sin.5>sin85度
答:sinasin(60-a)sin(60+a)=1/4sin3a
答:…sin85=m,得cos85cos75cos65cos55……cos5=m,sin10sin30sin50sin70sin90sin110sin130sin150sin170=2^9*m*2 (sin10sin30sin50sin70)^2=2^9*m*2 sin10sin50sin70=2^(11/2)*m 得cos20cos40cos80=2^(11/2)*m,2^(11/2)*m=1/8,所以m=2^(-17/2)

利用计算器比较sin1.5和sin85度的大小 “sin1.5”指的是什么嘛? -
26192车融
:[答案] 1.5是代表弧度数,sin1.5就是1.5弧度的正弦值. sin1.5≈0.997495 sin85°≈0.996195 ∴ sin1.5>sin85°
