### Math 302, Non-Euclidean Geometry, Fall 1997

There are two sections of this course, meeting at
11am and at 3pm on MWF, in Altgeld 243, and taught
by Prof. John Sullivan.
The syllabus
is available here online; the homework problems
will also be listed online as they are assigned.
Note that the original printed syllabus had a misprint; the homework
is actually worth 30% of the course grade.
The solutions to the homework will generally be available after
it is due; solutions to the homework due Nov 17 and earlier are now online.

The final exam for this course will be 8-11am Mon 15 Dec for
the 11am section, and 7-10pm Thu 18 Dec for the 3pm section. If you
need to take the exam at the other time, this is OK, but please check
with me. There will be two review sessions in 141 Altgeld:
11am-12 Sat 13 Dec, and 11:30-12:30 Wed 17 Dec.

If you want to

Occasionally, Math 302 has met on Fridays (at the usual times) in the
Renaissance Experimental
Laboratory (REL) in the Beckman Institute. REL is room 3414 on the third
floor of Beckman. There we can look at computer demos.

The first hour exam was held in class on Friday 19 September,
covering material in Chapters 4 and 5 of Martin's book.
The scores were somewhat low; the curve was 90s=A, 80s=A-, 70s=B+,
60s=B, 50s=B-, 40s=C+, 30s=C, 20s=C-. There are now solutions for the test online.

The second hour exam was held on Friday 17 October, covering
material through chapter 13. The median score was just below 50.
The line between A/B was 65, between B/C was 45, and between C/D was 25.
Because we went over all the problems in class, solutions will not be
posted. Remember that on Friday 24 October, you should turn in
your test again with correct answers to all the questions on the back.

The third hour exam was held in class on Friday 21 November,
covering material in Chapters 14 and 17-20. The median grade was 28,
and the curve was 32-40=A, 26-31=B, 20-25=C.

There is a nice version of
Euclid's Elements
available online at Clark University, with interactive figures.
Look for instance at the constructions for the
incircle and
circumcircle of a triangle.

We also looked at web pages illustrating hyperbolic triangles
and Penrose
tilings.
