SYNOPSIS
#include <math.h>
double sinh (double x); float sinhf (float x); long double sinhl (long double x); double cosh (double x); float coshf (float x);
long double coshl (long double x); double tanh (double x); float tanhf (float x); long double tanhl (long double x);
STANDARDS
Interfaces documented on this reference page conform to industry standards as follows:
cosh(): XPG4
sinh(): XPG4
tanh(): XPG4
Refer to the standards(5) reference page for more information about industry standards and associated tags.
DESCRIPTION
The sinh(), sinhf(), and sinhl() functions compute the hyperbolic sine of x. Both sinh(x), sinhf(x), and sinhl(x) are defined as (exp(x) -
exp(-x))/2.
The cosh(), coshf(), and coshl() functions compute the hyperbolic cosine of x. Both cosh(x), coshf(x), and coshl(x) are defined as (e**x
+ e**(-x))/2.
The tanh(), tanhf(), and tanhl() functions compute the hyperbolic tangent of x. Both tanh(x), tanhf(x), and tanhl(x) are defined as (e**x
- e**(-x))/(e**x + e**(-x)).
The following table describes function behavior in response to exceptional arguments:
