           Summary: When a correct answer is entered, the problem gives
                    the code "Can't generate enough valid points for
                    comparison"

The user enters the derivative correctly as
-15*([sin(ln(x))]^(-6))*cos(ln(x))*(1/x).  The answer is marked incorrect with
the code "Can't generate enough valid points for comparison".  It appears that
Webwork is testing the answer outside the domain of the function.  Thank you!
