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 find the order-one Bessel function of the second kind with the help of Y1() 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 Y1() function.
Syntax:
func Y1(a float64) float64
- If you pass +Inf in this function like Y1(+Inf), then this function will return 0.
- If you pass 0 in this function like Y1(0), then this function will return -Inf.
- If the value of a<0, then this function will return NaN.
- If you pass NaN in this function like Y1(NaN), then this function will return NaN.
Example 1:
// Golang program to illustrate // the use of math.Y1() function package main import ( "fmt"
"math"
) // Main function func main() { // Finding the order-one Bessel
// function of the second kind
// Using Y1() function
res_1 := math.Y1(-3)
res_2 := math.Y1(6)
res_3 := math.Y1(math.Inf(1))
res_4 := math.Y1(math.NaN())
res_5 := math.Y1(4.6)
res_6 := math.Y1(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)
fmt.Println( "Result 6: " , res_6)
} |
Output:
Result 1: NaN Result 2: -0.17501034430039827 Result 3: 0 Result 4: NaN Result 5: 0.2737452414709432 Result 6: -Inf
Example 2:
// Golang program to illustrate // the use of math.Y1() function package main import ( "fmt"
"math"
) // Main function func main() { // Finding the order-one Bessel
// function of the second kind
// Using Y1() function
nvalue_1 := math.Y1(0.89)
nvalue_2 := math.Y1(6)
// Sum of the given numbers
res := nvalue_1 + nvalue_2
fmt.Printf( "%.3f + %.3f = %.3f" ,
nvalue_1, nvalue_2, res)
} |
Output:
-0.883 + -0.175 = -1.058
