As is the case with most students (I suppose), I seem to have lost touch with the do doing some "basic" math -- calculating integrals, playing around with matrices and doing some linear algebra etc. -- as I have proceeded through my undergraduate program. To be honest, I didn't practice a whole lost of questions when I took these introductory courses, so I presume that's one source from where this issue stems.
I'm a student of physics with a mathematical leaning. Ideally, I don't want to go through a mathematical methods textbooks for physicists/engineers since they're pretty superficial (at times) and are more like "here's-a-result-now-go-solve-problems." At the same time, I don't think I have the time to sit through very long textbooks, such as James Stewart's Calculus.
Any suggestions of textbooks, given my aforementioned concerns, where one can "practice" calculus, linear algebra, complex analysis etc. to stay in touch with the practice of being able to solve in questions in closed form.
