       sinh, sinhf, sinhl - hyperbolic sine function

SYNOPSIS

       float sinhf(float x);
       long double sinhl(long double x);

       Link with -lm.

DESCRIPTION
       The  sinh() function returns the hyperbolic sine of x, which is defined
       mathematically as:

           sinh(x) = (exp(x) - exp(-x)) / 2
