C library function - sinh()

Description

The C library function double sinh(double x) returns the hyperbolic sine of x.

Declaration

Following is the declaration for sinh() function.

double sinh(double x)

Parameters

• x -- This is the floating point value.

Return Value

This function returns hyperbolic sine of x.

Example

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

#include <stdio.h>
#include <math.h>

int main ()
{
   double x, ret;
   x = 0.5;

   ret = sinh(x);
   printf("The hyperbolic sine of %lf is %lf degrees", x, ret);
   
   return(0);
}

Let us compile and run the above program, this will produce the following result:

The hyperboloc sine of 0.500000 is 0.521095 degrees
