The function is defined in <cmath> header file.
[Mathematics] sinh x = sinh(x) [In C++ Programming]
sinh() prototype [As of C++ 11 standard]
double sinh(double x); float sinh(float x); long double sinh(long double x); double sinh(T x); // For integral type.
The sinh() function takes a single argument in radians and returns the hyperbolic sine of that angle in double, float or long double type.
The hyperbolic sine of x is given by,
sinh() Parameters
The sinh() function takes a single mandatory argument representing a hyperbolic angle in radian.
sinh() Return value
The sinh() 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 HUGE_VAL with the proper sign, and an overflow range error occurs.
Example 1: How sinh() function works?
#include <iostream>
#include <cmath>
using namespace std;
int main()
{
double x = 3.55, result;
result = sinh(x);
cout << "sinh(x) = " << result << endl;
// x in Degrees
double xDegrees = 90;
x = xDegrees * 3.14159/180;
result = sinh(x);
cout << "sinh(x) = " << result << endl;
return 0;
}
When you run the program, the output will be:
sinh(x) = 17.3923 sinh(x) = 2.3013
Example 2: sinh() function with integral type
#include <iostream>
#include <cmath>
using namespace std;
int main()
{
int x = -3;
double result;
result = sinh(x);
cout << "sinh(x) = " << result << endl;
return 0;
}
When you run the program, the output will be:
sinh(x) = -10.0179
