So I have been interested in trying to do some physics that require more heavy use of calculus. I plan on getting Kleppner's mechanics book as well as Purcells E&M book. Having been out of school for so long, I need to brush up on my calculus, and I was wondering what the best approach would be for getting ready. I have Thomas and Finney 9th edition calculus book which I used during my undergraduate study 15 years ago. Based on this calculus book, I was wondering how heavily I should dive into the problems. And which chapters I should stress more than others. I have gone through about a quarter of the book and doing about a dozen problems in each section, with the expectation that I will get more practice with these concepts when I tackle the Kleppner book. I am also curious about if this calculus book is enough to really get into the physics books mentioned. My initial goal was to get through Young and Freedman's University Physics book and then get a modern physics book. But now I am interested in really revisiting mechanics and electromagnetism more deeply. But I realize that tackling problems of this difficulty will need a bit more math prep work, I believe. Any guidance on how best to efficiently get through the Calculus prep work would be appreciated. Thanks!
