valarray cosh() function in C++ Last Updated : 24 Oct, 2018 Summarize Comments Improve Suggest changes Share Like Article Like Report 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:- CPP // C++ program to demonstrate // example of cosh() function. #include <bits/stdc++.h> using namespace std; int main() { // Initializing valarray valarray<double> varr = { 0, 0.25, 0.5, 0.75, 1 }; // Declaring new valarray valarray<double> varr1; // use of cosh() function varr1 = cosh(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 : 1 1.03141 1.12763 1.29468 1.54308 Example 2:- CPP // C++ program to demonstrate // example of cosh() function. #include <bits/stdc++.h> using namespace std; int main() { // Initializing valarray valarray<double> varr = { 0.2, 0.14, 1.0, 0.0 }; // Declaring new valarray valarray<double> varr1; // use of cosh() function varr1 = cosh(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 : 1.02007 1.00982 1.54308 1 Comment More infoAdvertise with us Next Article valarray abs() function in C++ B bansal_rtk_ Follow Improve Article Tags : Misc C++ CPP-Functions cpp-valarray Practice Tags : CPPMisc Similar Reads valarray cos() function in C++ The cos() function is defined in valarray header file.
