I gave you, contrary to my principles, a complete camera ready proof.
If you cannot follow that proof, then you need to have a serious sit down with a tutor.

ok thanks alot.
I live in the caribbean and my tutor himself is unsure when he gives a lecture.
Any tips on how to learn this induction?
are there any pdfs where it is explained clearly?

I thought Plato's proof explained it clearly. I don't think there are any PDFs out there that would explain it more clearly than that.
