## Mathematical tools for the physical sciences

MWF 15:10-16:00, 241 Cory Hall

### Resources

• Books.
• Mathematics for physicists by Susan M. Lea, Publisher: Thomson Brooks/Cole, 2004. ISBN 0-534-37997-4
• Mathematical Methods in the physical sciences by Mary L. Boas, Publisher: Wiley Text Books; 2 edition, 1983. ISBN: 0-471-04409-1;
• Mathematical physics by Eugene Butkov, Publisher: Benjamin Cummings, 1968. ISBN: 0-201-00727-4

The first book is the main textbook for the course. All three books are on reserve in the library.

The instructor welcomes cooperation among students and the use of books . However, handing in homework that makes use of other people's work (be it from a fellow student, a book or paper, or whatever) without explicit acknowledgement is considered academic misconduct.
