cosh() function is a library function of cmath header, it is used to find the hyperbolic cosine of the given value (hyperbolic angle), it accepts a number (x) and returns the hyperbolic cosine of x.
COSH()函数是CMATH报头的库函数，它被用于查找给定值(双曲角)的双曲余弦，它接受一个数字(x)和返回x的双曲余弦。
Syntax of cosh() function:
cosh()函数的语法：
cosh(x);Parameter(s): x – is the number (hyperbolic angel) to be used to calculate the hyperbolic cosine.
参数： x –是用于计算双曲余弦的数字(双曲天使)。
Return value: double – it returns double type value that is the hyperbolic cosine of hyperbolic angle x.
返回值： double-返回双精度类型值，即双曲角度x的双曲余弦值。
Example:
例：
Input: float x = 2.45; Function call: cosh(x); Output: 5.83732 C ++代码演示cosh()函数的示例 (C++ code to demonstrate the example of cosh() function) // C++ code to demonstrate the example of // cosh() function#include <iostream>#include <cmath>using namespace std;// main() sectionint main(){ float x; x = -10.23; cout<<"cosh("<<x<<"): "<<cosh(x)<<endl; x = 0; cout<<"cosh("<<x<<"): "<<cosh(x)<<endl; x = 2.45; cout<<"cosh("<<x<<"): "<<cosh(x)<<endl; return 0;}Output
