Salve!
I got myself a copy of Spivak's Calculus because I wanted to learn Calculus right & as far as the text goes, it's marvellous. It's very fresh, especially for a 30-40 year old text, & the main body of the text, so far, has helped me a lot. I've learned a lot of calculus from other books, apart from some integration stuff which I'm going over in Thomas' Calculus concurrently.
I know enough Calc to get away with doing well in Physics, so far, and am continuing to learn.
But, my problem comes from the end of chapter questions. As you would expect, a lot of people complain about the difficulty of these questions due to the demands they place on the student to "shape up" & I don't mean to be one of them but I've only been studying mathematics for about 8-9 months after a lifetime of failing basic math in school.
I don't want to skimp on Spivak as I know that the rewards will be great but how can I be expected to give three analogous proofs to the Schwarz Inequality? How can I obtain the Lagrange Interpolation formula? I can't even do Lagrangians in mechanics yet, let alone Interpolations...
I've never been exposed to any kind of book that explains how to go about doing these things. You can't do abstract algebra without precursors & you can't do calculus without precursors.
I've heard W.G. Hardy's book A Course in Pure Mathematics would teach me some of what I'm looking for. Can you sympathise with my situation & perhaps give some guidance?

Read the reviews, they MADE me get this book. The high esteem it gets, I mean, if you conquer it you'd feel like a prince.
I am just looking for the literature one would read in order to grasp what Spivak is talking about in the questions section.
Like I said, the written part is easy to follow and you can extrapolate from the main body of the text to prove a good few of the end of chapter statements.
I'll be buying Hardy's book tomorrow anyway, both Spivak's Calculus & Hardy's Pure Mathematics are Calculus & an intro to Real Analysis, (from what I've read online), so we'll just have to wait & see.
Anyway, it's been 30 hours of study mixed with shopping and snow, time to sleep... after some Kleppner...
