Historical note, January 2014
I taught Math 436 in Fall 1993, shortly before I first built a website. (The Mosaic browser was released in 1993, and the World Wide Web Consortium was founded in 1994.) Consequently, my class materials from Fall 1993 have not previously been available online.
I have recompiled the three Math 436 examinations from Fall 1993. Here are links to those exams.
