Usage and example of the C library function sinh()

C Standard Library - <math.h>

C Library Function double sinh(double x) Returns x hyperbolic sine.

Declaration

Below is the declaration of the sinh() function.

double sinh(double x)

Parameter

• x 　-- Floating-point value.

Return Value

This function returns the hyperbolic sine of x.

Online Example

The following example demonstrates the usage of the sinh() function.

#include <stdio.h>
#include <math.h>
#define PI　3.141592654
int main()
{
　　　　double angle =　2.50, result;
　　　　result = sinh(angle);
　　　　printf("%.2Hyperbolic sine (in radians) of 'lf' = %.2lf", angle, result);
　　　　return 0;
}

Let's compile and run the above program, which will produce the following result:

%.2Hyperbolic sine (in radians) of 'lf' =　2.50
