What are some books for learning the techniques of Calculus?

[Adesh]

We have so many great books available for Calculus, such as : Spivak's Calculus, Stewart Calculus, Thomas Calculus , Gilbert Strang's Calculus, Apostol's Calculus etc.
These books are very nice but they teach you the concepts well and all the standard techniques that are available for solving the Calculus problems. What I'm looking for is a book which focuses on some techniques for solving the problems, by this I mean techniques like those differentiation under integral sign (Feynman's Technique) (I want to add a little side note over here, somewhere I read that Feynman said that he got a book on calculus which taught that technique of differentiation under integral sign but his Professor never taught that technique and hence he was better at integration than his class fellows). One more technique which I can mention is L'Hopital's rule.
So, which book should I go for if I want to learn the kinds of techniques which I have mentioned above and of course many others assuming that my concepts are clear (I can say my concepts are clear only for academics otherwise there lies a whole philosophy of calculus to read about).
Thank you.

My first calculus text was Strang's, and it included L'Hopital's Rule. It also included numerous bibliographic references to more advanced literature. And the math professor was a physicist.

What’s your personal recommendation from those references listed there?

I'd recommend looking at Prof. Terrence Tao's work -- he strikes me as transcendently brilliant -- his writing makes difficult material apprehensible to regular bright people.

But that’s just 116 pages long book which just contains personal ways of solving the problems. Can you please cite some more books?

Click on the 'Books' link -- 17 books are listed there -- I liked the logic exposition in #10.
