ARCOSH(x)


Arguments

x

specifies a numeric constant, variable, or expression.

Range: x >= 1

Details

The ARCOSH function computes the inverse hyperbolic cosine. The ARCOSH function is mathematically defined by the following equation, where x >= 1:

[equation]


Examples

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
