MathMate,
I cannot get to the link:
(Broken Link Removed)
but I get access to
http://isis.poly.edu/courses/discretemath/
If it is a problem on the Rosen book, just give me the chapter, page and problem number, and perhaps the first five words of the question for verification (they differ between editions).
You could also double check on the last part of the link.
Thanks.
