sinh, sinhf—hyperbolic sineSynopsis
#include <math.h> double sinh(double x); float sinhf(float x);
Description
sinh computes the hyperbolic sine of the argument x.
Angles are specified in radians. sinh(x) is defined as
(exp(x) - exp(-x))/2
sinhf is identical, save that it takes and returns float values.
Returns
The hyperbolic sine of x is returned.
When the correct result is too large to be representable (an
overflow), sinh returns HUGE_VAL with the
appropriate sign, and sets the global value errno to
ERANGE.
Portability
sinh is ANSI C.
sinhf is an extension.
