I have order: Calculus an Intuitive and Physical Approach, and It is due to arrive tomorrow. I had wanted to buy it because I wanted to learn some physics along with the calculus however now I am starting to think that maybe it was a bad choice since I was thinking that it wasn't a very good book, it might not explain things well or it won't teach me all of the calculus 1 that a pure calculus book would. Have any of you used this book before? I can always send it back and buy a pure calculus book. P.S I am self teaching it.
