# Finding the Hyperbolic Sine of Complex Number in Golang

• Last Updated : 01 Apr, 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 hyperbolic sine of the specified complex number with the help of Sinh() 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 Sinh() function.

Syntax:

`func Sinh(y complex128) complex128`

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

Example 1:

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

Output:

```Result 1: (0.33336013894799293-1.4796974784869428i)
Result 2: (0.5277083119608631+3.722159332384543i)
Result 3: (0.4890562590412937-1.4031192506220405i)
```

Example 2:

 `// Golang program to illustrate how to find the``// hyperbolic sine of the specified complex number``package main`` ` `import (``    ``"fmt"``    ``"math/cmplx"``)`` ` `// Main function``func main() {`` ` `    ``cnumber_1 := complex(0, 2)``    ``cnumber_2 := complex(4, 6)`` ` `    ``// Finding hyperbolic sine``    ``cvalue_1 := cmplx.Sinh(cnumber_1)``    ``cvalue_2 := cmplx.Sinh(cnumber_2)`` ` `    ``// Sum of two hyperbolic sine values``    ``res := cvalue_1 + cvalue_2`` ` `    ``// Displaying results``    ``fmt.Println(``"Complex Number 1: "``, cnumber_1)``    ``fmt.Println(``"Hyperbolic sine 1: "``, cvalue_1)`` ` `    ``fmt.Println(``"Complex Number 2: "``, cnumber_2)``    ``fmt.Println(``"Hyperbolic sine 2: "``, cvalue_2)``    ``fmt.Println(``"Sum : "``, res)`` ` `}`

Output:

```Complex Number 1:  (0+2i)
Hyperbolic sine 1:  (-0+0.9092974268256816i)
Complex Number 2:  (4+6i)
Hyperbolic sine 2:  (26.202967617830907-7.630343482807812i)
Sum :  (26.202967617830907-6.72104605598213i)
```
