Finding Arcsine of the Specified Number in Golang

Last Updated : 01 Apr, 2020

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 are allowed to find the arcsine of the specified number with the help of Asin() 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 Asin() function.

Syntax:

func Asin(y float64) float64

If the value of y < -1 or y > 1, then Asin(y) = NaN
If you pass 0 in this function, then this function will return 0.

Example 1:

// Golang program to illustrate how
// to find arcsine of the given number
  
package main
  
import (
    "fmt"
    "math"
)
  
// Main function
func main() {
  
    // Finding arcsine of the given value
    // Using Asin() function
    res_1 := math.Asin(1)
    res_2 := math.Asin(-1)
    res_3 := math.Asin(0)
    res_4 := math.Asin(3)
  
    // Displaying the result
    fmt.Printf("Result 1: %.1f", res_1)
    fmt.Printf("\nResult 2: %.1f", res_2)
    fmt.Printf("\nResult 3: %.1f", res_3)
    fmt.Printf("\nResult 4: %.1f", res_4)
}

Output:

Result 1: 1.6
Result 2: -1.6
Result 3: 0.0
Result 4: NaN

Example 2:

// Golang program to illustrate how
// to find arcsine of the given number
  
package main
  
import (
    "fmt"
    "math"
)
  
// Main function
func main() {
  
    // Finding arcsine 
    // of the given value
    nvalue_1 := math.Asin(1)
    nvalue_2 := math.Asin(-1)
  
    // Sum of the given values
    res := nvalue_1 + nvalue_2
  
    // Displaying results
    fmt.Printf("%.1f + %.1f = %.1f", 
           nvalue_1, nvalue_2, res)
  
}

Output:

1.6 + -1.6 = 0.0
