Need good math methods for physics book

[frogjg2003]

I am a first year physics graduate student. I double majored in math and physics, so I wasn't required to take a math methods in physics course. Looking at the course that was offered at my undergraduate institution, the only topics it covered that I am only deficient in are complex analysis and heat flow.
The textbook for that course was Mathematical Methods in the Physical Sciences by Boas. Is that a good book? Are there other good math methods books out there as well.

I think Boas is pitched at just the right level of rigor (or lack of it; she tends to omit proofs) for getting up to speed quickly.

Boas is a nice book, but in my opinion Hassani is much better..

 

[frogjg2003]

Thank you. Is Hassani as (more) rigorous as Boas?

 

[chill_factor]

yes but more rigorous =/= more useful. boas is fine.

Well, actually there are two "Hassani's"
There is "Mathematical Methods: For Students of Physics and Related Fields"
https://www.amazon.com/dp/0387095039/?tag=pfamazon01-20
this one is not very rigorous (same as Boas), but it has some very nice explanations.
It's my favorite math-methods book.

The other one is "Mathematical Physics, A Modern Introduction to its Foundations"
https://www.amazon.com/dp/0387985794/?tag=pfamazon01-20
more advanced and rigorous but still a very nice book

Just go to your library and see which one you like..
