Calculus is the most advanced topic I have encountered in math. The book that I am using is clear as can be, but it has so many definitions and theorems.
I would like to have all the most crucial definitions and theorems in note or list form so that I can review them efficiently. Should I make it by myself (write it down) or can I download it somewhere?
What is best practice for learning calculus? How should I know what is most crucial?
Any help would be appreciated.
Calculus is all about practise. If you have a book you're studying from, make summaries and do as many exercises as you can. You cannot read a Calculus book like a novel, but need to understand every concept before passing on to the next one, because it all builds up. Good luck
