The cosh() function for complex number is defined in the complex header file.This function is the complex version of the cosh() function. This function is used to calculate the complex hyperbolic cosine of complex number z and returns the cosh of complex number z. Syntax:
template<class T> complex<T>
cosh (const complex<T>& z );
Parameter:
- z: This method takes a mandatory parameter z which represents the complex number.
Return value: This function returns the cosh() of complex number z. Below programs illustrate the cosh() function in C++:
Program 1:-
C++
#include <bits/stdc++.h>;
using namespace std;
int main ()
{
complex< double > complexnumber (0.0, 1.0);
cout << "The cosh of" << complexnumber << "is "
<< cosh (complexnumber) << endl;
return 0;
}
|
Output
The cosh of(0,1)is (0.540302,0)
Example 2:-
C++
#include <bits/stdc++.h>;
using namespace std;
int main ()
{
complex< double > complexnumber (1.0, 0.0);
cout << "The cosh of " << complexnumber << "is "
<< cosh (complexnumber) << endl;
return 0;
}
|
Output
The cosh of (1,0)is (1.54308,0)
Time Complexity: O(1)
Auxiliary Space: O(1)
