Does anyone know of a good resource for these types of problems? I took an Intro to Real Analysis class as an undergrad and didn't do so well in it, but now I am working back through the book, and it is making A LOT more sense than it did back then. However, I was looking for some worked out examples, and possibly graphing, to help me understand this stuff better as I go through it. . . Does anyone know of a good book / site? Thanks!!
