Yes, I'm aware for this problem. If you search for 'carom maths' you seem to get there okay. I guess I need to speak to my webspace provider to upgrade my security. Thanks for flagging this up.

Maths teacher friends - I've just revised my Carom resources, 40 pure extracurricular maths PowerPoints bridging from A Level to University Maths. Great for a sixth form maths club. Everything available for free - google 'carom maths' or try www.carom-maths.co.uk

Unexpected email from Jonny Griffiths telling me there's a new 2026 update of his RISPS book, that's great investigations for impressionable A Level students. Download it now from www.risps.co.uk with links to Geogebra and Excel files @jonny-griffiths.bsky.social

Worked hard on a big revision of my risps. Weeding out mistakes, making tasks clearer, writing Geogebra and Excel files, all with better navigation; look out for the free eBook coming out in January!

Found this task somewhere on the net recently. I have an answer but my method is a bit tortured! Does anyone have a nice technique for this?
