I have received several correct

based on the earliest submission. Regarding the actual winning solution

all...

February 2004 problem PDF, LaTeX
February 2004 winner: Mr. Jeffrey
Gaither
Winning solution: PDF
Textbook solution: PDF
Comments from the coordinator: I have received only one
submission which has
been determined to qualify as a correct solution. It still contains
though some
intuitive arguments as far as properties of functions judged through
the behavior of their derivatives. Therefore, in addition to the actual winning
solution, I also
provide another solution, which is short and yet rigorous.
January 2004 problem PDF, LaTeX
January 2004 winner: Mr. Paul Smith

submissions altogether and and each one contained a correct solution!

December 2003 problem PDF, LaTeX
December 2003 winner: Not declared
Correct solution: PDF
Comments from the coordinator: I have received two
submissions that contained
discussion on convergence of the sequence $x_n=\cos(x_{n-1})$. This
discussion may potentially lead to a correct proof, provided that the
convergence is established rigorously. However, my determination is
that the arguments in either of the submissions did not qualify as the
full proof.
November 2003 problem PDF, LaTeX
November 2003 winner: Mr. John Deszyck
Winning solution: PDF

submissions that did contain
some correct thoughts but have stopped a little short of a full-blown
correct solution. I have also received a more comprehensive solution
that was submitted later than the winning solution posted here. Enjoy
the next month problem and have Happy Holidays!

solution was submitted just several hours after the problem was posted.
The next solution, which also was correct, was submitted by the
previous month winner three hours later. The race is getting tight :-).
I know of a different correct solution, not the same as the winning
solution posted here.
