# Finding the Inverse Sine of Complex Number in Golang

• Last Updated : 27 Mar, 2020

Go language provides inbuilt support for basic constants and mathematical functions for complex numbers with the help of the cmplx package. You are allowed to find the inverse sine of the specified complex number with the help of the Asin() function provided by the math/cmplx package. So, you need to add a math/cmplx package in your program with the help of the import keyword to access the Asin() function.

Syntax:

`func Asin(x complex128) complex128`

Let us discuss this concept with the help of the given examples:

Example 1:

 `// Golang program to illustrate how to find``// the Inverse Sine of Complex Number``package main`` ` `import (``    ``"fmt"``    ``"math/cmplx"``)`` ` `// Main function``func main() {`` ` `    ``// Finding inverse sine of the``    ``// specified complex number``    ``// Using Asin() function``    ``res_1 := cmplx.Asin(3 + 5i)``    ``res_2 := cmplx.Asin(-4 + 8i)``    ``res_3 := cmplx.Asin(-8 - 7i)`` ` `    ``// Displaying the result``    ``fmt.Println(``"Result 1:"``, res_1)``    ``fmt.Println(``"Result 2:"``, res_2)``    ``fmt.Println(``"Result 3:"``, res_3)``}`

Output:

```Result 1: (0.5339990695941702+2.4598315216234306i)
Result 2: (-0.4611616352523445+2.886039504947561i)
Result 3: (-0.849771617866465-3.0565545070216835i)
```

Example 2:

 `// Golang program to illustrate how to find``// the Inverse Sine of Complex Number`` ` `package main`` ` `import (``    ``"fmt"``    ``"math/cmplx"``)`` ` `// Main function``func main() {`` ` `    ``cnumber_1 := complex(5, 7)``    ``cnumber_2 := complex(6, 9)`` ` `    ``// Finding inverse sine``    ``cvalue_1 := cmplx.Asin(cnumber_1)``    ``cvalue_2 := cmplx.Asin(cnumber_2)`` ` `    ``// Sum of two inverse sine values``    ``res := cvalue_1 + cvalue_2`` ` `    ``// Displaying results``    ``fmt.Println(``"Complex Number 1: "``, cnumber_1)``    ``fmt.Println(``"Inverse sine 1: "``, cvalue_1)`` ` `    ``fmt.Println(``"Complex Number 2: "``, cnumber_2)``    ``fmt.Println(``"Inverse sine 2: "``, cvalue_2)``    ``fmt.Println(``"Final sum: "``, res)`` ` `}`

Output:

```Complex Number 1:  (5+7i)
Inverse sine 1:  (0.617064296675988+2.846288828208389i)
Complex Number 2:  (6+9i)
Inverse sine 2:  (0.5860350919197013+3.075060767946888i)
Final sum:  (1.2030993885956893+5.921349596155277i)
```
