The C header file math.h contains the standard math library functions that can be used for performing various mathematical operations. The asinh function returns the arc hyperbolic sine of x in radians.
Library Function asinh of math.h Header File
atan(x) = \sinh^{-1}(x)
Declaration of asinh function
double asinh(double x)
Parameters of asinh function
The asinh function accepts a single input argument which can be any value from negative to positive.
| Parameter | Description |
|---|---|
| double value | This value of double function ranges from -\infty\;to\; \infty |
Return value of asinh function
The asinh function returns a value in radians and it’s type is double. The function returns NaN if the parameter passed to asinh function does not lies in the valid range of value.
| Parameter | Return Value |
|---|---|
| -\infty< x \leq -1 or 1\leq x< \infty | It returns the value in radians. |
| NaN | NaN (not a number) |
Implementation of Library Function math.h asinh
The following code shows the use of asinh function.
#include <stdio.h>
#include <math.h>
#define PI 3.141592654
int main()
{
float number = 9.0;
double return_value;
return_value = asinh(number);
printf("Inverse of sinh(%.2f) function = %.2f in radians", number, return_value);
// Converting radians to degree
return_value=(return_value*180)/PI;
printf("\nInverse of sinh(%.2f) function= %.2f in degrees", number, return_value);
return 0;
}
Output:
Inverse of sinh(9.00) function = 2.89 in radians Inverse of sinh(9.00) function= 165.78 in degrees
