math.Yn() Function in Golang With Examples

Go language provides inbuilt support for basic constants and mathematical functions to perform operations on the numbers with the help of the math package. You can the order-n Bessel function of the second kind the help of Yn() function provided by the math package. So, you need to add a math package in your program with the help of the import keyword to access the Yn() function.

Syntax:

func Yn(a int, b float64) float64
  • If you pass +Inf in this function like Yn(a, +Inf), then this function will return 0.
  • If the value of a≥0 like Yn(a≥0, 0), then this function will return -Inf.
  • If the value of b<0 like Yn(a, b<0), then this function will return NaN.
  • If the value of a<0 like Yn(a<0, 0), then this function will return +Tnf(if a is odd) or -Inf(if a is even).
  • If you pass NaN in this function like Yn(a, NaN), then this function will return NaN.

// Main function
func main() {
  
    // Finding the order-n Bessel 
    // function of the second kind
    // Using Yn() function
    res_1 := math.Yn(-3, -2)
    res_2 := math.Yn(6, 3)
    res_3 := math.Yn(1, 1.1)
    res_4 := math.Yn(1, math.NaN())
    res_5 := math.Yn(-1, 0)
  
    // Displaying the result
    fmt.Println("Result 1: ", res_1)
    fmt.Println("Result 2: ", res_2)
    fmt.Println("Result 3: ", res_3)
    fmt.Println("Result 4: ", res_4)
    fmt.Println("Result 5: ", res_5)
  
}
