Mathematics 121B, Spring 2013

Professor: Richard Borcherds

Office hours: TuTh 9:30-11:00 927 Evans Hall

This class meets in 6 Evans Hall, 11:00-12:30, Tuesdays and Thursdays. This is the course home page (address /~reb/121B).

Catalogue Description: Mathematics 121B

Prerequisites: Math 53 and 54. Special functions, series solutions of ordinary differential equations, partial differential equations arising in mathematical physics, probability theory. Intended for students in the physical sciences who are not planning to take more advanced mathematics courses.

Textbook:

Mathematical methods in the physical sciences by M. L. Boas, third edition, ISBN:9780471198260, published by Wiley. (You can get copies of the older 2nd edition on the web for about $20 and these are also fine for the course except that a few of the homework problems are renumbered: see the link at the bottom of this page for details.) Math 121B will cover chapters 11, 12, 13, and 15 of the textbook.

Grading:

The grading will probably be somthing like homework 40%, midterms 15% each, and final 30% of the grade. The final grade is not based on a curve or on previously fixed marks for certain grades. Instead the average grade for the course will be based on my judgement of how well the class is doing, and will be high if everyone is working hard at the homework and doing well on the exams.

Almost all the questions in the midterms or finals will be randomly selected questions from the book similar to homework questions, possibly with the constants in the questions changed. So if you understand how to do all the homework questions you will be able to do all the questions on the exams.

I only change grades for exams or quizzes if there is a clear error on the part of the grader, such as adding up marks incorrectly or forgetting to grade a question. Grades for incomplete answers will never be increased, because this is unfair to students who do not ask for their grades to be increased. I will not increase grades just because someone needs a higher grade to graduate or get into some program.

The final homework grade will be computed from the grades for the 10 or so best homeworks, so it does not matter much if you forget one or two.

Examinations:

You may use a pocket calculator in the exams. You may also bring one sheet of paper with writing on both sides to the exams. Apart from this one sheet, the exams are "closed book". The final will be mostly on the material covered after the second midterm, though there will be some problems on earlier material. Students who have been given special accomodation for the exams will take them in room 959 Evans Hall, starting at the same time as everyone else.

Homework:

Homework is due by the end of the Thursday lecture 1 week after it is assigned. Late homework will not be accepted. About half the marks for homework will be based on the number of questions that you made a serious attempt on, and about half will be based on more detailed marking of a few questions. Collaboration on homework is fine, but if you hand in similar homework to your collaborator you should clearly state so and say who you are working with, in order to avoid unfortunate misunderstandings.
