Thanks in advance for any help,(adsbygoogle = window.adsbygoogle || []).push({});

I'm trying to understand epsilon-delta proofs, and the various sites I've found so far aren't helping that well. I know that epsilon is referring to a small number >0, and delta traditionally refers to a number > epsilon, but I'm not quite sure of why this extra variable is required.

Much appreciated,

Ryan
