-FUNCTION
-<<acosh>>, <<acoshf>>---inverse hyperbolic cosine 
-
-INDEX
-acosh
-INDEX
-acoshf
-
-ANSI_SYNOPSIS
-	#include <math.h>
-	double acosh(double <[x]>);
-	float acoshf(float <[x]>);
-
-TRAD_SYNOPSIS
-	#include <math.h>
-	double acosh(<[x]>)
-	double <[x]>;
-
-	float acoshf(<[x]>)
-	float <[x]>;
-
-DESCRIPTION
-<<acosh>> calculates the inverse hyperbolic cosine of <[x]>.
-<<acosh>> is defined as 
-@ifinfo
-. log(<[x]> + sqrt(<[x]>*<[x]>-1))
-@end ifinfo
-@tex
-$$ln\Bigl(x + \sqrt{x^2-1}\Bigr)$$
-@end tex
-
-<[x]> must be a number greater than or equal to 1.
-
-<<acoshf>> is identical, other than taking and returning floats.
-
-RETURNS
-<<acosh>> and <<acoshf>> return the calculated value.  If <[x]> 
-less than 1, the return value is NaN and <<errno>> is set to <<EDOM>>.
-
-You can change the error-handling behavior with the non-ANSI
-<<matherr>> function.
-
-PORTABILITY
-Neither <<acosh>> nor <<acoshf>> are ANSI C.  They are not recommended
-for portable programs.
