First time for me here so kindly let me know if I violate the rules - especially if this is a duplicate.

After reading the page how to become a good theoretical phycist, I started a serious revision of calculus. For exercises, Math.SE is a good place. I was attempting exercises from this user (question s/he asked and answered) and realized I couldn't solve the majority of them.

So the question is what is the level of mastery of calculus required for physics? What is(are) the best book(s) for that? I'm interested in limits, integration and infinite series for now.

Background: standard mathematics with limits, integration, infinite series, differential equations (ODEs and PDEs) and numerical analysis and optimization. Everything was fast paced because professors wanted to finish the program as fast as possible ( during 3 semesters ) so I really never got good at any of the listed above.
Note: self-study kind of books will be most helpful.

Background: engineering student, studied standard mathematics with limits, integration, infinite series, differential equations (ODEs and PDEs) and numerical analysis and optimization. Everything was fast paced because professors wanted to finish the program as fast as possible ( during 3 semesters ) so I really never got good at any of the listed above. Note: I'm learning physics not as part of college but because it is a too beautiful area of science to live without knowing a thing or two in it. So self-study kind of books will be most helpful.
