Textbook references for PHYS 2502 Mathematical Physics

Textbooks at the level of this course

These are textbooks I might have adopted for this course. There are very many options, but I like each of the following very much. I've come to rely especially on the book by Riley, Hobson, and Bence.

Mathematical Methods for Physics and Engineering: A Comprehensive Guide, 3rd Edition, by K. F. Riley, M. P. Hobson, and S. J. Bence.
Mathematical Methods in the Physical Sciences, 3rd Edition, by Mary L. Boas
Mathematical Tools for Physics, by James Nearing
The link takes you to a free PDF that you can download, but also shows you where to buy an inexpensive hard copy from Dover Books
A Course in Mathematical Methods for Physicists, by Russell L. Herman (a Temple undergraduate Physics alumnus)
