Returns the inverse hyperbolic cosine.
- x
-
specifies a numeric constant, variable, or expression.
The ARCOSH function computes the inverse hyperbolic
cosine. The ARCOSH function is mathematically defined by the following equation,
where x >= 1:
The following example computes the inverse hyperbolic cosine.
data _null_;
x=arcosh(5);
x1=arcosh(13);
put x=;
put x1=;
run;
SAS writes the following output to the log:
x=2.2924316696
x1=3.2566139548
