Hi everyone! In this period i'm trying to understand how proofs work.(adsbygoogle = window.adsbygoogle || []).push({});

And i don't understand why the induction process is only used sometimes. When can i use it ?

For example in the euclid's theorem http://en.wikipedia.org/wiki/Euclid's_theorem

why this could not be proven with the induction ?
