Perth Mod sessions are back from Monday 4 May, but, alas, sessions at UWA, may not be back until next semester (that's July?!). I'll let you know, if I can get them back earlier. If you normally come Wednesdays, but could come on Mondays check the directions.
Some of you will have noticed that there are now mini i-lectures for all of Chapter 12 on geometry. I also inserted AIMO 2013 Q8 which is a Bowtie Th (Power of a Point) question, as a new Q40 in Ex Set 12, which means the last few problems become Q41-43.
Currently, I'm recording mini i-lectures for Chapter 11 on inequalities, and some on vectors (Chapter 13), because it's the way I like to explain the Cauchy-Schwarz Inequality. The i-lectures generally are below.
The first few inequalities i-lectures are up. The rest may take a while, since I seem to have reached some limits, which is slowing down the process of down/up-loading, and youtube-ing. When we start back on Monday, I'll try to record those and make those into mini i-lectures as well. Apologies for not having extended the solutions for AMO 2020. I think we should concentrate on those on Monday, and maybe also review the last Tournament of the Towns.
I have just proof-read the next Tournament of the Towns. The rest of Australia will apparently do it, with students `self-supervising' at home. The AMT will still issue certificates, but thes scripts won't be passed on to Moscow, not that we had been getting much joy out of that anyway. I guess we'll do the same, unless something changes radically in the next week or so.
With regard to the geometry problems in Chapter 12 and the inequalities problems of Chapter 11, despite the existence of mini i-lectures, I would much rather new students did the problems without viewing the mini i-lectures and sending me solution attempts as a JPEG or PDF in an email, and having me critique your solutions. Why? ... It takes a lot of discipline to not look at a solution, before one's made a genuine attempt, and it has a tendency to stifle creativity. Sometimes, you will come up with a different solution that's just as good, or sometimes better than my solution. (Ordinary level uni. students never seem to 'get' that.)
You may be wondering who is in the room when I'm recording mini i-lectures. It's a former student from Curtin, who had been interested in maths olympiad problems, but never got the opportunity to do any of it while at highschool.
