In this C++ tutorial, you will learn how to find hyperbolic cosine of given angle using cosh() function of cmath, with syntax and examples.
C cosh
C++ cosh() returns hyperbolic cosine of angle given in radians.
Syntax
The syntax of C++ cosh() is
cosh(x)
where
| Parameter | Description |
|---|---|
| x | A 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.
