sinh

NAME

sinh, sinhf, sinhl - hyperbolic sine function

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

I float sinhf(float  x );

I long double sinhl(long double  x );

Link with -lm.

The R sinh () function returns the hyperbolic sine of x, which is defined mathematically as (exp(x) - exp(-x)) / 2.

SVr4, 4.3BSD, C89. The float and long double variants are C99 requirements.
