 Here you will find information concerning the Business Algebra (1090-4) class for the Fall 2003 Semester, which meets on Monday, Wednesday, and Friday 9:40AM-10:30AM in LS 102. If you have any doubts, problems, concerns, etc., feel free to send a message to the instructor.

 Final Exam: the results will be available on Thursday 12/11. I will be in my office from 9 to 11 AM. Otherwise, you can contact me by email to make an appointment to pickup your test. Notice that I will be out of town from 12/19 to 1/2. Two More Points! Everybody got two extra points on Test 3 in connection with the "closed + bounded" issue in problem (3b). So, for example, if your test grade was 57/74 it is now 59/74. But, please, if a problem like this arises on the final exam don't forget to check (and say!) if the region is closed and bounded. Problem Sessions! Beginning Tuesday 10/7, every Tuesday 5-6PM we will meet in LCB 215 to discuss problems or answer any other questions that you may have. This is not mandatory and should not be considered part of the course: the only goal is to provide extra time for those who want to practice. More information will be posted here as it becomes available.
