Lately, I have been experiencing a sort of anxiety over not understanding some of these proofs in my calculus textbook. I just finished a calculus I course, and we did not spend any time learning them; so, I thought, since it is summer time now, I would go back over and try to learn those different theorems and their corresponding proofs. But I just don' seem to understand them. Is this normal, to not learn the proofs to different theorems in a Calculus I class? One person who works as a tutor at my school said that I shouldn't worry all that much about learning these proofs, especially since I haven't taken a logic course (I believe that is what see referred to it as). Is this true? Should I just continue to learn new material, get a better intuition for calculus, and then eventually go back and learn the proofs?
