asinh() function in C++ STL

The asinh() is an inbuilt function in C++ STL which returns the inverse hyperbolic sine of an angle given in radians.

Syntax:

asinh(data_type x)

Parameter: The function accepts one mandatory parameter x which specifies the inverse hyperbolic angle in radian. It can be any value i.e. negative, positive or zero. The parameter can be of double, float or long double datatype.

Return Value: This function returns the inverse hyperbolic sine of the argument in radians.

Below programs demonstrate the above function:



Program 1:

// C++ program to demonstrate
// the asinh() function
#include <bits/stdc++.h>
using namespace std;
  
int main()
{
    double x = 50.0;
  
    // Function call to calculate asinh(x) value
    double result = asinh(x);
  
    cout << "asinh(50.0) = " << result << " radians" << endl;
    cout << "asinh(50.0) = " << result * 180 / 3.141592
         << " degrees" << endl;
    return 0;
}

Output:

asinh(50.0) = 4.60527 radians
asinh(50.0) = 263.863 degrees

Program 2:

// C++ program to demonstrate
// the asinh() function
#include <bits/stdc++.h>
using namespace std;
  
int main()
{
    int x = -50.0;
  
    // Function call to calculate asinh(x) value
    double result = asinh(x);
  
    cout << "asinh(-50.0) = " << result << " radians" << endl;
    cout << "asinh(-50.0) = " << result * 180 / 3.141592
         << " degrees" << endl;
    return 0;
}

Output:

asinh(-50.0) = -4.60527 radians
asinh(-50.0) = -263.863 degrees

Errors and Exceptions: The function returns no matching function for call to error when a string or character is passed as an argument.
Program 3:

// C++ program to demonstrate
// the asinh() function
#include <bits/stdc++.h>
using namespace std;
  
int main()
{
    string x = "gfg";
  
    // Function call to calculate asinh(x) value
    double result = asinh(x);
  
    cout << "asinh(50.0) = " << result << " radians" << endl;
    cout << "asinh(50.0) = " << result * 180 / 3.141592
         << " degrees" << endl;
    return 0;
}

Output :

prog.cpp:11:25: error: no matching function for call to 'asinh(std::__cxx11::string&)'
  double result = asinh(x);
