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 functionfunc 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 functionfunc 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
