C++ cosh()

C++ cosh() returns hyperbolic cosine of angle given in radians.

Syntax

The syntax of C++ cosh() is

cosh(x)

where

ParameterDescription
xA double, float, long double, or integral type value representing angle in radians.

Returns

The return value depends on the type of value passed for parameter x.

The return value of cosh(x) is

  • double if x is double or IntegralType.
  • float if x is float.
  • long double if x is long double.

The synopsis of cosh() function is

double cosh(double x);
float cosh(float x);
long double cosh(long double x);
double cosh(T x); // for integral type argument values

cosh() is a function of cmath library. Include cmath library at the start of program, if using cosh() function.

Example

In this example, we

C++ Program

#include <iostream>
#include<cmath>
using namespace std;

int main() {
    double x;
    cout << "Enter angle (radians) : ";
    cin >> x;
    
    double result = cosh(x);
    cout << "cosh(" << x << ") : " << result << endl;
}

Output

Enter angle (radians) : 2
cosh(2) : 3.7622
Program ended with exit code: 0
Enter angle (radians) : 0
cosh(0) : 1
Program ended with exit code: 0
Enter angle (radians) : -2
cosh(-2) : 3.7622
Program ended with exit code: 0

Conclusion

In this C++ Tutorial, we learned the syntax of C++ cosh(), and how to use this function to find the hyperbolic cosine of given angle, with the help of examples.
