sinh() function in C++ STL

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

Syntax :

sinh(data_type x)

Parameter :The function accepts one mandatory parameter x which specifies the hyperbolic angle in radian. The parameter can be of double, float or long double datatype.

Return Value: The function returns the hyperbolic sine of the argument. If the magnitude of the result is too large to be represented by a value of the return type, the function returns inf.

Program 1:

// C++ program to demonstrate the
// sinh() function
#include <bits/stdc++.h>
using namespace std;

int main()
{
    double x = 4.1;

    double result = sinh(x);
    cout << "sinh(4.1) = " << result << endl;

    // x in Degrees
    double xDegrees = 90;
    x = xDegrees * 3.14159 / 180;

    result = sinh(x);
    cout << "sinh(90 degrees) = " << result << endl;

    return 0;
}

Output:

sinh(4.1) = 30.1619
sinh(90 degrees) = 2.3013

Program 2:

// C++ program to demonstrate the
// sinh() function
#include <bits/stdc++.h>
using namespace std;

int main()
{
    int x = -4;

    double result = sinh(x);
    cout << "sinh(-4) = " << result << endl;

    // x in Degrees
    double xDegrees = 90;
    // convert to radians
    x = xDegrees * 3.14159 / 180;

    result = sinh(x);
    cout << "sinh(90 degrees) = " << result << endl;

    return 0;
}

Output:

sinh(-4) = -27.2899
sinh(90 degrees) = 1.1752

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

Below programs illustrate the errors and exceptions of sinh() method:

Program 3:

// C++ program to demonstrate the
// sinh() function when a string is passed
#include <bits/stdc++.h>
using namespace std;

int main()
{
    string x = "gfg";
    double result;

    result = sinh(x);
    cout << "sinh(x) = " << result << endl;

    return 0;
}

Output:

prog.cpp:14:20: error: no matching function for call to 'sinh(std::__cxx11::string&)'
result = sinh(x);

Program 4:

// C++ program to demonstrate the sinh()
// function When argument is too large
#include <bits/stdc++.h>
using namespace std;

int main()
{
    double x = 3000.0;

    double result = sinh(x);
    cout << "sinh(x) = " << result << endl;

    return 0;
}

Output:

sinh(3000.0) = inf
