sinh() function in C++ STL
C++ STL Function : sinh()
The sinh() function uses a mathematical formula to calculate the hyperbolic sine of a number. This formula involves the use of exponential functions and involves the ratio of the sides of a right triangle in a hyperbolic coordinate system.In this section, we will discuss about library function sinh() in STL which is used in C++.The Standard Template Library(STL) is a set of complete data structures and functions which can be used in C++.
Library Function sinh() in C++
In C++ programming language, the sinh function is included in standard template library.
The range of input argument which is passed to floor function is not limited here as it can be any value such as float or long double also.
Declaration of sinh function
sinh(data_type x)
Parameters of sinh function
The sinh function accepts a single input argument which is the hyperbolic angle and can be a double/float or long double value.
| Parameter | Description |
|---|---|
| Hyperbolic angle | This value of the parameter can be of double / float or long double type. |
Return value of sinh function
The sinh function returns the hyperbolic sine value of the argument passed.
| Parameter | Return Value |
|---|---|
| Hyperbolic sine of the argument passed | It returns the value in double / float or long double type. |
Implementation of STL Function sinh() in C++
Example 1:
The following code shows the use of 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;
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
Example 2:
#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
