187 – Mathematics – Stack Exchange

I have mentioned a few times the website http://math.stackexchange.com/ and suggested that you take a look at it and use it as a resource. I believe it is a really useful site when used appropriately. Some of you have asked for additional references, and I think this site may help supply some of them.

Here is a short list of questions posted on the site that may give you an idea of its value:

• Proof by strong induction.
• Proof by induction for inequality.
• Proving a theorem in classical propositional logic.
• Understanding proof by contradiction.
