# valarray sinh() function in C++

• Last Updated : 24 Oct, 2018

The sinh() function is defined in valarray header file. This function is used to calculate hyperbolic sine of the value of each element in valarray and returns a valarray containing the hyperbolic sine of all the elements.

sinh(varr);

Parameter: This function takes a mandatory parameter varr which represents valarray.

Returns: This function returns a valarray containing the hyperbolic sine of all the elements.

Below programs illustrate the above function:

Example 1:-

 // C++ program to demonstrate// example of sinh() function.  #include using namespace std;  int main(){      // Initializing valarray    valarray        varr = { 0, 0.25, 0.5, 0.75, 1 };      // Declaring new valarray    valarray varr1;      // use of sinh() function    varr1 = sinh(varr);      // Displaying new elements value    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 :
0 0.252612 0.521095 0.822317 1.1752

Example 2:-

 // C++ program to demonstrate// example of sinh() function.  #include using namespace std;  int main(){      // Initializing valarray    valarray        varr = { 0.2, 0.14, 1.0, 0.0 };      // Declaring new valarray    valarray varr1;      // use of sinh() function    varr1 = sinh(varr);      // Displaying new elements value    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 :
0.201336 0.140458 1.1752 0
