If you have an Android smart phone then the app "Model Scale Calculator" is very useful. Available on Google Playstore.

I find my O-Level Maths (1964 version) works quite well.

Was only a year behind you Buccaneer.............no slide rules, calculators weren't commercially available....just simple trig tables like the Romans used  O0........ Derek

extract from WIKI....

Early trigonometry
The ancient Egyptians and Babylonians had known of theorems on the ratios of the sides of similar triangles for many centuries. However, as pre-Hellenic societies lacked the concept of an angle measure, they were limited to studying the sides of triangles instead

Yassou Derek,
Sounds a bit Greek to me.
We were allowed to buy and use a calculator for study and exams when I attend Queensland Institute of Technology.
Calculator a Sharp, was the only one approved, just did main functions and cost $350.00 back in 1975. >>:-( >>:-( >>:-(

They now give them away for couple bucks <*< <*< <*<

Hello Derek,

Yes it was Trig Tables only up to O level. When we moved to the sixth Form and started A level Maths we were allowed to have a Slide Rule. Mine came from WH Smiths in a plastic case. This didn't last long so I made a leather one from Mum's old handbag. Slide Rule and case still reside at the back of my desk drawer. 52 years old in September and all the moving parts still work!
