go Y1()

math.Y1()方法语法

func Y1(x float64) float64

go源码对Y1()方法的介绍：

Y1 returns the order-one Bessel function of the second kind.

Special cases are:

Y1(+Inf) = 0
Y1(0) = -Inf
Y1(x < 0) = NaN
Y1(NaN) = NaN

golang模块中math.Y1()方法，可用于返回参数x的1阶的第二类贝塞尔函数。除此之外，Y1(+Inf) = 0；Y1(0) = -Inf；Y1(x < 0) = NaN；Y1(NaN) = NaN。

func main() {
	var y1 float64 = math.Y1(5.2)
	fmt.Println(y1)
}

运行go文件，得到输出：
