SINH(3) 						     Linux Programmer's Manual							   SINH(3)

NAME
sinh, sinhf, sinhl - hyperbolic sine function SYNOPSIS
#include <math.h> double sinh(double x); float sinhf(float x); long double sinhl(long double x); Link with -lm. Feature Test Macro Requirements for glibc (see feature_test_macros(7)): sinhf(), sinhl(): _BSD_SOURCE || _SVID_SOURCE || _XOPEN_SOURCE >= 600 || _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L; or cc -std=c99 DESCRIPTION
The sinh() function returns the hyperbolic sine of x, which is defined mathematically as: sinh(x) = (exp(x) - exp(-x)) / 2 RETURN VALUE
On success, these functions return the hyperbolic sine of x. If x is a NaN, a NaN is returned. If x is +0 (-0), +0 (-0) is returned. If x is positive infinity (negative infinity), positive infinity (negative infinity) is returned. If the result overflows, a range error occurs, and the functions return HUGE_VAL, HUGE_VALF, or HUGE_VALL, respectively, with the same sign as x. ERRORS
See math_error(7) for information on how to determine whether an error has occurred when calling these functions. The following errors can occur: Range error: result overflow errno is set to ERANGE. An overflow floating-point exception (FE_OVERFLOW) is raised. CONFORMING TO
C99, POSIX.1-2001. The variant returning double also conforms to SVr4, 4.3BSD, C89. SEE ALSO

NAME
cosh, coshf, coshl - hyperbolic cosine function SYNOPSIS
#include <math.h> double cosh(double x); float coshf(float x); long double coshl(long double x); Link with -lm. Feature Test Macro Requirements for glibc (see feature_test_macros(7)): coshf(), coshl(): _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L || /* Since glibc 2.19: */ _DEFAULT_SOURCE || /* Glibc versions <= 2.19: */ _BSD_SOURCE || _SVID_SOURCE DESCRIPTION
These functions return the hyperbolic cosine of x, which is defined mathematically as: cosh(x) = (exp(x) + exp(-x)) / 2 RETURN VALUE
On success, these functions return the hyperbolic cosine of x. If x is a NaN, a NaN is returned. If x is +0 or -0, 1 is returned. If x is positive infinity or negative infinity, positive infinity is returned. If the result overflows, a range error occurs, and the functions return +HUGE_VAL, +HUGE_VALF, or +HUGE_VALL, respectively. ERRORS
See math_error(7) for information on how to determine whether an error has occurred when calling these functions. The following errors can occur: Range error: result overflow errno is set to ERANGE. An overflow floating-point exception (FE_OVERFLOW) is raised. ATTRIBUTES

C99, POSIX.1-2001, POSIX.1-2008. The variant returning double also conforms to SVr4, 4.3BSD. BUGS
In glibc version 2.3.4 and earlier, an overflow floating-point (FE_OVERFLOW) exception is not raised when an overflow occurs. SEE ALSO
