sinh()

The sinh() function returns the hyperbolic sine of an argument given in radians.

sinh(angle)

The angle parameter should be expressed in radians. To convert from degrees to radians:

radians = degrees * PI / 180

The following example uses sinh() to return the hyperbolic sine of 0.0 in radians:

#include <iostream>
#include <cmath>

int main() {
  double x = 0.0;
  double result;

  result = std::sinh(x);

  std::cout << "The hyperbolic sine of " << x << " radians is " << result << "\n";
  // Output: The hyperbolic sine of 0 radians is 0
}
