C++ Math cosh
The function finds the hyperbolic cosine of an angle given in radian.
Mathematically,
Syntax
Suppose the hyperbolic angle is 'x':
Example
float cosh(float x);
double cosh(double x);
long double cosh(long double x);
double cosh(integral x);
Parameter
x : The value of angle whose hyperbolic cosine is to be calculated.
Return value
It returns the hyperbolic cosine of angle given in radian.
Example 1
Let's see a simple example when the value of x is of integral type.
Example
#include <iostream>
#include<math.h>
using namespace std;
int main()
{
int x=45;
float radian=x*3.14/180;
std::cout << "Value of degree is :" <<x<<std::endl;
cout<<"cosh(radian): "<<cosh(radian);
return 0;
}
Output:
Output
Value of degree is :45
cosh(radian): 1.32426
In this example, cosh computes the hyperbolic cosine of an angle 45 and returns the value 1.324.
Example 2
Let's see another simple example.
Example
#include <iostream>
#include<math.h>
using namespace std;
int main()
{
float x=25.5;
float radian=x*3.14/180;
std::cout << "Value of degree is: " << x<<std::endl;
cout<<"cosh(radian): "<<cosh(radian);
return 0;
}
Output:
Output
Value of degree is: 25.5
cosh(radian): 1.10058
