EXCEL里面设公式
A2=A1+15;B2=A2/180*3.14159265;C2=ROUND(SIN(B2),2)
D2==ROUND(COS(B2),2);E2==ROUND(TAN(B2),2)
360° | 270°| 0°| 15° | 30° | 37°| 45°
sin | 0 | -1 | 0 |(√6-√2)/4 | 1/2 | 3/5 |√2/2
cos | 1 | 0 | 1 |(√6+√2)/4 |√3/2 | 4/5 |√2/2
tan | 0 | 无值 | 0 | 2-√3 |√3/3 | 3/4 | 1
哥们,你要是真的想知道,用计算器,按那么几下,不是都出来了吗?何必这么复杂呢?
套公式啊
