## 在弧度和度数之间转换
|
||
|
||
### 通用配方
|
||
|
||
以下公式可用于在弧度和度数之间进行转换：
|
||
```
|
||
r = d * (π / 180)
|
||
|
||
d = r * (180 / π)
|
||
|
||
where r is the angle in radians and d is the angle in degrees.
|
||
```
|
||
|
||
### 例子
|
||
|
||
将2π/ 3弧度转换为度数：
|
||
```
|
||
2π/3 * 180/π = 360π/3π = 360/3 = 120 degrees
|
||
```
|
||
|
||
将30度转换为弧度：
|
||
```
|
||
30 * π/180 = 30π/180 = π/6 or (1/6)π radians
|
||
|
||
Note: Radians are usually expressed in terms of π instead of a rounded decimal as this form represents the actual value rather than an approximation.

||
