### sinh -- Calculate Hyperbolic Sine

Format

>     #include <math.h>
>     double sinh(double x);

Language Level: ANSI, POSIX, XPG4
sinh calculates the hyperbolic sine of x, with x expressed in radians.

Return Value
sinh returns the value of the hyperbolic sine of x. If the result is too large, sinh sets errno to ERANGE and returns the value HUGE_VAL (positive or negative, depending on the value of x).

Example
This example computes y as the hyperbolic sine of pi/2.

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

    int main(void)
    {
       double pi, x, y;

       pi = 3.1415926535;
       x = pi/2;
       y = sinh(x);

       printf("sinh( %lf ) = %lf\n", x, y);
       return 0;
