NAME
+
       acos - arc cosine function
+
+
SYNOPSIS
+
       #include <math.h>
+
+       double acos(double x);
+
+
DESCRIPTION
+
       The  acos()  function calculates the arc cosine of x; that
+       is the value whose cosine is x.  If x  falls  outside  the
+       range -1 to 1, acos() fails and errno is set.
+
+
RETURN VALUE
+
       The  acos() function returns the arc cosine in radians and
+       the value is mathematically defined to be between 0 and PI
+       (inclusive).
+
+
ERRORS
+
       EDOM   x is out of range.
