在线 反正切函数(x) 计算器。反正切计算器。
The 反正切gent function is the inverse function of y = tan(x).
反正切(y) = tan-1(y) = x+ kπ
对于每个
k = {...,-2,-1,0,1,2,...}
例如，如果45°的正切值是1：
tan(45°) = 1
Then the 反正切gent of 1 is 45°:
反正切(1) = tan-1(1) = 45°
| y | x = 反正切(y) | |
|---|---|---|
| 度 | 弧度ians | |
| -1.732050808 | -60° | -π/3 |
| -1 | -45° | -π/4 |
| -0.577350269 | -30° | -π/6 |
| 0 | 0° | 0 |
| 0.577350269 | 30° | π/6 |
| 1 | 45° | π/4 |
| 1.732050808 | 60° | π/3 |
