Luke,

In the future, please do not post complete (or nearly complete)
homework solutions to the list.  Try to find a slightly more indirect
way to ask your question -- we're happy to answer, we just don't want
copy/paste solutions floating around.  For now, though, here are the
results I get with your code:

Welcome to Racket v5.0.99.5.
> (require "31.3.1.rkt")
-0.4974659600326926
-0.49746596003269405
-4974659600326926.0
-4974659600326941.0

Those look different to me.  Try subtracting one from the other to see
how different.  Or, show us the results you get if you don't get the
same results.
