Question

@TuringTest, @across, @JamesJ: do you know what is a good book to better my understanding of real analysis?

Answer 1

I know that @JamesJ would vouch for \(\text{Spivak's Calculus}\), and so would I. Have you given that text a look?

Answer 2

As Spivak says in the introduction to that book, it would have better if he had titled the book "An Introduction to Analysis". It's very, very solid.
