# asin() function for complex number in C++

• Last Updated : 11 Oct, 2018

The asin() function for complex number is defined in the complex header file.This function is the complex version of the asin() function. This function is used to calculate the complex arc sine of complex number z and returns the arc sine of complex number z.

Syntax:

```template<class T> complex<T>
asin (const complex<T>& z );
```

Parameter: This method takes a mandatory parameter z which represents the complex number.

Return value: This function returns the arc sine of complex number z.

Below programs illustrate the asin() function in C++:

Example 1:

 `// c++ program to demonstrate``// example of asin() function.`` ` `#include ``using` `namespace` `std;`` ` `// driver program``int` `main()``{``    ``complex<``double``> complexnumber(-2.0, 0.0);`` ` `    ``// use of asin() function for complex number``    ``cout << ``"The asin of "``         ``<< complexnumber``         ``<< ``" is "``         ``<< ``asin``(complexnumber)``         ``<< endl;`` ` `    ``return` `0;``}`
Output:
```The asin of (-2,0) is (-1.5708,1.31696)
```

Example 2:-

 `// c++ program to demonstrate``// example of asin() function.`` ` `#include ``using` `namespace` `std;`` ` `// driver program``int` `main()``{``    ``complex<``double``> complexnumber(-2.0, -0.0);`` ` `    ``// use of asin() function for complex number``    ``cout << ``"The asin of "``         ``<< complexnumber``         ``<< ``" is "``         ``<< ``asin``(complexnumber)``         ``<< endl;`` ` `    ``return` `0;``}`
Output:
```The asin of (-2,-0) is (-1.5708,-1.31696)
```
