Course News and Homework Hints

End-of-course update. Final Course Grades were transmitted to the Registrar on Saturday afternoon, June 28. Overall, final exam grades were good. The range of scores was 34 (17%) to 184 (92%), with mean 138, just about the same as those for the midterm exams. Eleven of the 20 students who took the final exam were able to take advantage of the redemptive feature of the grade-calculation program: their performance on the final exam was better than that on the midterms, and so their midterm average increased prior to calculation of the final grades.

Final exam grade distribution: 179-184 (A): 2; 175 (A-); 169-171 (B+): 2, 161-166 (B): 4; 155 (B-); 147-148 (C+): 2; 120 (C-); 111-117 (D): 3; 103 (D-): 2; 34-78 (F): 2.

Course grade distribution: A: 2, A-: 3; B+: 4; B: 1; B-: 2; C: 2; D+: 1; D: 3; F: 3. Median course grade: B-.

Registrar's Statement about PeopleSoft System Access. E-mail message of June 24 from the Registrar:
Registration for Fall semester is currently unavailable for continuing undergraduate students during the New Student Orientation period. Access to registration will resume for continuing undergraduate students on July 7. That access will be interrupted for all users in late July and early August as the University installs a new release of the PeopleSoft Student Administration System. The Student Administration System will be unavailable from 5 PM on Thursday, July 24, until approximately 8 AM on Monday, August 11.

Maple TA Practice for Exam 2 A mini-practice exam (85 points) is available at the Maple TA Web site for Math 210Q students. Note. The questions are not clones of exam questions, but rather are designed to stimulate thought about key ideas that do arise on the exam. They strike the instructor as useful practice items for studying for the test. In entering answers, be sure to use the asterisk (*) to indicate multiplication: 3*x instead of 3x, for example. You do not need to register for the class on the Website in order to try the practice exam, which you can access by selecting "Practice Exam 2". This is a new experimental system, so may have bugs. If you encounter any, don't panic, but instead send the instructor an e-mail with a description of your problem. To try the practice exam, click on the following link. You can also access Maple TA from any Web browser by copying in the following URL (That is not a misprint at the end; it's the Spring course for which access was established originally.): http://www.mapleserver.com/mapleta/classes/UConnMath221/

Maple worksheets for the course are available. If you have Maple installed on your computer, you should be able to download a worksheet, and run it on that computer. The worksheet QuadricSurfs2.mws has a successful plot of the hyperboloid of two sheets from Exercise 16, Section 3.6, which the instructor's unfortunate editing of built-in range bounds distorted in class. The plot shown was generated from the original code, edited only by changing the equation. Moral: before tinkering, try the original settings, which were set after considerable experimenting a few years ago.

Mathematica notebooks for the course are available. As with the Maple worksheets, if you have Mathematica on your computer you should be able to download and run these notebooks. The first one illustrates cylindrical-coordinate plotting.
