sinh, sinhf—hyperbolic sine #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.
You can modify error handling for these functions with matherr.
Portability
sinh is ANSI C.
sinhf is an extension.
