You can use the AM-GM inequality (the first result) to prove a really nice circle geo theorem/result. I've made it a question but I'm saving it for later though (going to write my own trials if I have time).

I want to do this but I don't want to let the marathon die lol (even though its on the verge of death at the moment)

Re: HSC 2013 4U Marathon


This is a very simple 3U induction question, why did you post it here? I will show you how to do it. I promise you guys I will keep the thread alive. Realise and Si helped me a lot so this is me returning the favour.

Re: HSC 2013 4U Marathon

Are you sure that isn't the answer?

I thought the question is too difficult for students undertaking 4 units on maths so I posted the solution.
