Name
sinh, cosh, tanh - hyperbolic functions
Syntax
#include <math.h>

float fsinh(x)
float x;
double cosh(x)
double x;
float fcosh(x)

Description
These functions compute the designated hyperbolic functions for double and float data types.
Error
Below 2.4 ulps (unit in the last place).
Diagnostics
The and functions return +oo (and sinh may return -oo for negative x) if the correct value would overflow.
