Need help with my geometry

Great fun they were to use to. Interpolation used to be one of least enjoyable practices.

All thru high school, we all had a laminated sheet with log and sine, cosine, tangent tables on it that was provided by the US air force. They were very handy, I don't know what happened to mine, but of course we don't need them any more. I saw my first calculator after high school at the University Mo. at Rolla. It was made by Wang. It was the size of of small dormitory refrigerator and had about a dozen terminals around the room to do your calculations on. it had Nixie tubes (a type of high voltage gas discharge display tube) for a display. A year later I held a calculator in my hand. Technology really moved fast after LED's became available. LCD calculators came out a few years later. Soon they were blister packed at Wal Mart for a few bucks.

I bought my Casio FX 850P when I started college in 1988

I still use it today. The add-on memory module no longer works, but other than that it still works as good as the day I bought it.... Back in the day there were 2 schools of people. Those who favoured the HP calculator with its perculiar syntax, and the others who liked the WYSIWYG method employed by the Japanese.

I use my Casio 8R a few times a week and it still works perfect. I got it in the 70s.
I can see an LED readout much better than an LCD.

I did all my calculations by hand. I still can't find my slide rule.

How can a ruler with a sliding gauge be anything close to accurate????

Supposed to be close to 3 digits behind the decimal. The last digit is pretty "iffy". We did pretty good with them "back in the day"
