{\it Directions}
\bigskip
\item{$\bullet$} First 20 minutes: Each group makes up {\it three\/} 
integrals.  Any formula that can be integrated
{\it by the rules we have discussed in class so far -- that is: the power,
exponential, sin, cos, sum and constant multiple rules, and 
substitution -- possibly 
after some preliminary algebraic rearrangement\/} is OK.  
\medskip
\item{$\bullet$} Prepare an {\it answer key\/}, giving the answers 
for your integrals.  
\medskip
\item{$\bullet$}  Make an identical copy of your list of functions for 
each member of your partner group, and one answer key.
\medskip
\item{$\bullet$} Second 15 minutes: Each pair of partner groups exchanges 
functions.  Find the general antiderivatives of the functions you are given, working
as a group.  Prepare one set of solutions.
\medskip
\item{$\bullet$}  Final 15 minutes:  (The moment of truth!) Partner groups
combine and compare both sets of solutions with the answer keys to 
compute scores according to the rules below.
\bigskip
\noindent
{\it Scoring Rules}
\bigskip
\item{1)}  Each correct integral from your partner group 
you compute is worth 5 points.  
\medskip
\item{2)} If your group ``stumped'' your partner group, {\it and\/} 
you computed your integral correctly in the answer key, 
your group gets 3 bonus points.  
\medskip
\item{3)}  For each incorrect solution in your
group's answer key, though, you {\it lose\/} 5 points.  
\medskip
\item{4)}  Answers should still be counted as correct if they are 
equivalent to the answer key but in a different form (for example: written
with radicals rather than fractional powers).  
\medskip
\item{5)}  Best total group score ``wins'' the Derby.  (But of 
course, everyone wins in the end!)   
\medskip
\item{6)} The referee for any disputed call about whether a function
is legal or whether an answer is correct is Pr. Little.  It's OK
to ask the referee to make a ruling before you give your
problems to your partner group, if you are in doubt.
