asin() function for complex number in C++

Last Updated : 17 Aug, 2022

The asin() function for complex numbers 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:

cpp

// c++ program to demonstrate
// example of asin() function.

#include& lt; bits / stdc++.h & gt;
using namespace std;

// driver program
int main()
{
    complex& lt;
    double& gt;
    complexnumber(-2.0, 0.0);

    // use of asin() function for complex number
    cout& lt;
    <
    "
    The asin of& quot;
    <
    <
    complexnumber& lt;
    <
    "
    is& quot;
    <
    <
    asin(complexnumber) & lt;
    <
    endl;

    return 0;
}

Output:

The asin of (-2,0) is (-1.5708,1.31696)

Time Complexity: O(1)
Auxiliary Space: O(1)

Example 2:-

cpp

// c++ program to demonstrate
// example of asin() function.

#include <bits/stdc++.h>
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)

Time Complexity: O(1)
Auxiliary Space: O(1)
