ITrigonometricFunctions<TSelf>.CosPi(TSelf) 方法

定义

计算已被 倍数乘的值 pi的余弦值。

public:
 static TSelf CosPi(TSelf x);
public static abstract TSelf CosPi (TSelf x);
static member CosPi : 'Self -> 'Self
Public Shared Function CosPi (x As TSelf) As TSelf

参数

x
TSelf

值,以半旋转为单位,其余弦值要计算。

返回

TSelf

乘以 pix余弦值。

注解

这将计算 cos(x * π)
