double
cosh (double x
);
The cosh function computes the hyperbolic cosine of x. A range error occurs if the magnitude of x is too large.
The cosh function returns the hyperbolic cosine value.
#include <math.h>
double
sinh (double x
);
The sinh function computes the hyperbolic sine of x. A range error occurs if the magnitude of x is too large.
The sinh function returns the hyperbolic sine value.
None.
#include <math.h>
double
tanh (double x
);
The tanh function computes the hyperbolic tangent of x.
The tanh function returns the hyperbolic tangent value.
None.
