SOHCAHTOA still floats around in my head, decades later. Wish my teachers could have taught me my g/f’s birthday.

I’m sure you feel much better and all superior for having got that off your chest. Thanks for visiting.

Not simplifying formulae (and indeed, using degrees not radians), just looks amateurish. It’s pre-GCSE maths.

All the recommendations seem to be based on image height – I guess that’s because it’s easier to cover both traditional (4:3) and widescreen sets that way.

The ITU (International Telecommunications Union) recommends 3 time screen height for HD, and around 5 or 6 times for standard def. And yes, you’re right, in many cases for an optimum experience, people should really be sitting much closer than they appear to be.

Doh, I thought the recommended distance was no more than double the screen diagonal ?
This would result in cheapskates with 32″ sets watching TV whilst sitting on their coffee tables !

It’s a volcano, apparently. Or perhaps an island with a volcano. Once someone mentioned it in the office, it all came flooding back. But probably a quarter century since I did anything like that

Really, some teacher thought SOHCAHTOA would be an easy acronym to remember ? One of my teachers from decades ago taught us :
Our Athletic Team, Often Have Shields, And Hold Cups

Much easier to remember !
