ARCOSH

Syntax ARCOSH (x)
Location Hyper

This function returns the arc hyperbolic cosine of the specified value, that is to say it will return the value which must be passed to the hyperbolic cosine to return the given result, so:

COSH ( ARCOSH ( x )) = x

The ARCOSH function can be expressed as a combination of SuperBASIC keywords: it’s the same as:

LN(x + SQRT(x*x-1)).
