Last Updated :

The cosh() function is defined in valarray header file. This function is used to calculate hyperbolic cosine of the value of each element in valarray and returns a valarray containing the hyperbolic cosine of all the elements.
Syntax:
cosh(varr);
Parameter: This function takes a mandatory parameter varr which represents valarray.
Returns: This function returns a valarray containing the hyperbolic cosine of all the elements.
Below programs illustrate the above function:
Example 1:-
#include <bits/stdc++.h>
using namespace std;
int main()
{
valarray< double >
varr = { 0, 0.25, 0.5, 0.75, 1 };
valarray< double > varr1;
varr1 = cosh (varr);
cout << "The new valarray with"
<< " manipulated values is : "
<< endl;
for ( double & x : varr1) {
cout << x << " " ;
}
cout << endl;
return 0;
}
|
Output:
The new valarray with manipulated values is :
1 1.03141 1.12763 1.29468 1.54308
Example 2:-
#include <bits/stdc++.h>
using namespace std;
int main()
{
valarray< double >
varr = { 0.2, 0.14, 1.0, 0.0 };
valarray< double > varr1;
varr1 = cosh (varr);
cout << "The new valarray with"
<< " manipulated values is : "
<< endl;
for ( double & x : varr1) {
cout << x << " " ;
}
cout << endl;
return 0;
}
|
Output:
The new valarray with manipulated values is :
1.02007 1.00982 1.54308 1
