Physics 2210 - suggested texts.
There are many introductory classical mechanics texts out there. If you're having difficulties their different styles, perspectives, additional problems and examples may be very useful to you. Here are just a few suggestions:
Thornton and Marion- "Classical Dynamics of Particles and Systems" (This is often the text for Phys 2210, it is a similar level, perhaps a little more mathematically focused, than Taylor. This would be an excellent first choice to go to if you feel confused about a topic)
Hamill, "Intermediate Dynamics" (Another text very much at the level of ours)
Kleppner and Kolenkow, "Introduction to Mechanics". This is like an "honors freshman" level mechanics textbook, beautifully written.
For other math references besides Boas:
Ronald Tallarida, "Pocket Book of Integrals and Mathematical Formulas": an inexpensive little book filled with integral tables, trig identities, linear algebra - just a handy reference. (No explanations, it's just all the handy formulas in one place!)
Arfken and Weber "Mathematical Methods for Physicists" (a little bit higher level than Boas)
S. Lea, "Mathematics for Physicists" (comparable to Boas in level, a decent math text for physics)
Other books of possible interest for this course:
Feynman, Leighton, and Sands: "The Feynman Lectures on Physics, part I." (Part of a truly wonderful series of 3 "introductory" physics books, you should get a copy and read it!)
