cosh()
The cosh()
function returns the hyperbolic cosine of an argument given in radians.
Syntax
std::cosh(angle)
The angle
is measured in radians and the return type is a double
, float
, or long double
.
If the magnitude of the result is too large to express, the function returns HUGE_VAL
(positive or negative) and an overflow range error is thrown.
The mathematical formula used in cosh()
looks like this:
Example
This example uses cosh()
to return the hyperbolic cosine of 0.0
radians:
#include <iostream>#include <cmath>int main() {double x = 0.0;double result;result = std::cosh(x);std::cout << "The hyperbolic cosine of " << x << " radians is " << result << "\n";// Output: The hyperbolic cosine of 0 radians is 1}
Codebyte Example
This example uses cosh()
to return the hyperbolic cosine of 1.0
radians:
