Good textbook for better understanding calculus?

[armolinasf]

I've just completed calc 1, the book we used was Hughes-Hallett but I'm looking for a book that that really explains the concepts and gives me a deeper understanding of the subject. I'm seriously considering majoring in physics so I don't know if that would come into consideration when considering a book.

I've heard good things about Spivak and Courrant, but I'm worried that it may be too difficult, or would going through the normal calculus sequence using Hughes-Hallett be good enough preparation?

The other one I've looked at is Kline's calculus: an intuitive approach. It seems interesting because it attempts to explain concepts together with their physical applications How would this one compare with Spivak or Courant?

Thanks

Spivak's book is amazing. It is more of a maths book, but does include some references to their applications. I don't think the book is too hard to get through, but it's by no means an easy read, be prepared to spend a lot of time solving the problems he gives for a better understanding.
