asinh()

The asinh() function returns the inverse hyperbolic sine of an angle given in radians.

asinh(n)

The n parameter can be a floating-point value (e.g., a long or double) or an integral type (e.g., an int or bool).

This example uses the asinh() function to return the inverse hyperbolic sine of 3.14159:

#include <iostream>
#include <cmath>

int main() {
  double x = 3.14159;
  double result;

  result = std::asinh(x);

  std::cout << result << " radian" << "\n";
}

This example results in the following output:

1.8623 radian

This example uses the asinh() function to take an argument of 4.55 and return the inverse hyperbolic sine:
