Discussions: T Th 1-1:50pm, DMC 258.
Office hours: TBA in the Math Center
Beside the discussion sections, the TA is responsible for administering and grading quizzes and collecting and grading homeworks.
- Textbook: “Advanced Engineering Mathematics” by E. Kreyszig, Wiley. Any edition will work. The official version is the custom USC edition.
- Supplement: “Mathematics of Physics and Engineering” by Edward K. Blum and Sergey V. Lototsky, World Scientific, 2006 (ISBN-13: 9789812566218)
- Course goal: To realize that there is a lot of beautiful and useful mathematics out there beyond calculus and ordinary differential equations. In particular, we will cover all the material promised in the catalogue description of the course (Vector field theory; theorems of Gauss, Green, and Stokes; Fourier series and integrals; complex variables; linear partial differential equations; series solutions of ordinary differential equations), although not necessarily in this order. Here is an alternative look at it.
- Two very interesting books closely connected with the second half of the course:
- Nicholas J. Giordano, Physics of the piano. Oxford University Press, Oxford, 2010. 184 pp.
- Barry Mazur and William Stein, Prime numbers and the Riemann hypothesis. Cambridge University Press, Cambridge, 2016. xi+142 pp.
Save the dates! There will be two in-class one-hour exams (October 9 and November 20, both Wednesday, during regular lecture time). The two-hour final exam is Wednesday, December 18, 11am-1pm, in the regular lecture room SLH 100.
Homework, Quizzes, etc.: There will be 10 weekly quizzes (most Thursdays during the discussion sections), 11 homeworks (usually due on Tuesdays), and two computer projects (due Friday, October 25 and Friday, December 6). You should understand every solution to every homework problem and be ready to reproduce every solution without any help and in reasonable time. You are welcome to use any help whatsoever with the homework problems and the projects, but not with the quizzes.
Grading:
- Quizzes 15% total
- Homeworks, 15% total
- The projects, 10% total [5% each]
- Two Mid-Term Exams, 30% total [15% each]
- Final Two-Hour Exam, 30%
Approximate Grading Scheme. A: 90 and up; B: 80-89; C: 70-79. Pluses/minuses (As in A-, B+, etc.) will mostly be decided on a case-by-case basis.
Missed work. The general rule: no make-up exams or quizzes, and no late submissions of homeworks or the project (but early submissions, especially in electronic format, are welcome). Emergencies will be handled on a case-by-case basis. If you miss the final exam, with a valid excuse, you get an incomplete in the class; an incomplete is a major inconvenience for a number of people, including yourself, so, please, do not miss the final.
To encourage and reward consistent performance throughout the semester, I will not automatically drop any scores (such as the two lowest quizzes, etc.)
Students Requiring Special Accommodation
Any student requesting academic accommodations based on special needs is required to register with Office Of Student Accessibility Services (OSAS) each semester. A letter of verification for approved accommodations can be obtained from OSAS. Please be sure the letter is delivered to me (or to TA) as early in the semester as possible. OSAS is located in GFS 120. To contact OSAS: (213) 740-0776 [tel.], OSASFrontDesk@usc.edu [e-mail], on the web.
Academic Integrity
USC seeks to maintain an optimal learning environment. General principles of academic honesty include the concept of respect for the intellectual property of others, the expectation that individual work will be submitted unless otherwise allowed by an instructor, and the obligations both to protect one’s own academic work from misuse by others as well as to avoid using another’s work as one’s own. All students are expected to understand and abide by these principles. Scampus (the Student Guidebook) contains the Student Conduct Code in Section 11.00, while the recommended sanctions are in Appendix A.
