AMS 345/ CSE 355 Computational Geometry, Spring 2009

The course meets Mon/Wed, 2:20--3:40pm in Earth and Space 079.

All ARE Welcome!

Announcements:

5/11/09: I brought hard copies to the review session today of the following handout:
http://www.ams.sunysb.edu/~jsbm/courses/345/additional-problems-for-final.pdf
Recall that your final exam will be comprised of problems taken from:
1. hw5, hw6, hw7, hw8
2. the two practice finals (on the course website, with solutions)
3. the review sheet (on course website)
4. the list of additional problems (url above), which we went over in the review today. (No solutions are written up, but if you have specific questions after you attempt to solve them, feel free to ask. We did most of them on the board.)
The exam is closed book, closed notes.
Bring colored pencils/pens if you want for the drawings. A straightedge could be useful too.
The final will be 2:00-3:15pm on Wed, May 13, in Library E4320 (note the room!). Come early to get set up.
At 3:15-4:30, you may optionally take the Second Chance Midterm.

The final exam will be in Library E4320, 2:00, Wed, May 13. The first half (75 minutes) will be a noncummulative exam on hw 5-8 material; the second half of the period (3:15-4:30) will be for a second-chance retake of the midterm (see the course info sheet).
There will be a Review Session on Monday, May 11, 12:00-1:30 in Math P-131.

Our TA for the course is Shuai Shao (shsshao@gmail.com); office hours Mon 9:30-10:30am, Tues 3:30-4:30pm in Harriman 010.
My office hours are, tentatively, Mon (12:00-1:00), Tue (12:30-2:00), or email me for an alternate times, or whenever you drop by and I am free (don't be shy!)
