I've been trying to start teaching myself Calculus recently out of interest and the amount of useful info on PF is awesome but I can't seem to find a good way to actually start it off. As far as books are concerned, it seems that Stewart's is the standard but supposedly it's too watered down. Then I found Spivak's and Apostol's books which seem to be regarded as the best if you want to gain a deep understanding of Calculus. I was able to find a copy of Spivak's but it seems that it's mainly proving theorems and analysis than actual Calculus. As far as I know, Apostol's requires some previous calculus knowledge and even then it sounded like it was mainly proofs and analysis. I don't want to flood my brain with anything too advanced, I just wanna teach myself single variable calculus but at the same time I want to understand it really well, not just be able to solve the problems by memorizing steps... I might not have a strong mathematical background since I just finished grade 10 and we didn't learn any calculus yet, except for fundamental differentiation which was easy and useless by itself in a way. I'm a pretty good self learner, guess I'm just overwhelmed by all the information available and just looking for a place to start :) Sorry for the long post and thanks in advance for any advice or suggestions!
