How to introduce myself to Real Analysis? I'm starting college in a little over a month, and I'm going to be taking a combination Calculus and Real Analysis course. I've never had to do proofs in a math class, and I'm a bit nervous. I'd like to start introducing myself to Analysis; even a tiny head start would make me feel better. Is there a good cheap book or online resource of any kind that might help me prepare or even start to get me in the right mindset?
