I am starting my first year of undergraduate degree soon enough and the first course on mathematics would be Calculus 1. So, I am asking for some suggestions on the books I should use.
I already have fair bit of understanding about calculus from highschool/intermediate corses but not very rigorous.
Also, I am more concerned with self study
I am getting suggestions for Spivak and apostol (single variable) mainly, However if there are some other better texts then I would also look up to them. So which one should I prefer?
