I have studied calculus until line integrals and double integrals,and I think i quite understand the ideas and concepts,
but im afraid i haven't done as much excercises as i desired , and it has left the feeling that i might have a shaky foundation in these subjects and not the sufficient proficiency to study any further.
So what are some good and general problem set for me to have quick review on every subject starting from limits until the mentioned subject?
I have with me three textbooks, apostol's first volume,lithold's 3 volumes and G.H.Hardy's a course in pure mathematics.Which one would be suitable as a quick reminder of old subjects?
