Osage Orange (Maclura Pomifera). This tree's strong, springy wood was used by Native Americans to make hunting bows. It is a member of the mulberry family, and the fruits have a pleasant citrus smell, but unfortunately are not good to eat. (This image taken from .)

The text for this course is currently on reserve in the Mathematics Library, which is located on the 2nd floor of the Physical Sciences Center.



Sometimes I post an assignment in advance but change it in class the day before it's due. If you miss a class you should check this web page after class for the final version of the next day's assignment.

Suppose (f_n) is a sequence of continuous functions defined on a set A, and suppose f_n converges to a function f on A. Does it follow that f is also continuous on A? The answer depends on what you mean by "f_n converges to f on A", and the distinctions involved are a little subtle. Cauchy himself, the father of Real Analysis, seems to have tripped up on this point. See the article "Cauchy's Famous Wrong Proof", by V. Frederick Rickey.
