A 3,700-year-old clay tablet has proven that the Babylonians developed trigonometry 1,500 years before the Greeks and were using a sophisticated method of mathematics which could change how we calculate today.
The tablet, known as Plimpton 332, was discovered in the early 1900s in Southern Iraq by the American archaeologist and diplomat Edgar Banks, who was the inspiration for Indiana Jones.

You can secant you?
I can only see in a limited radius after somebody threw a pi in my face.
I am amazed these guys could do this math with clay tablets.
Imagine what they could do with pen and paper and a calculator.
If they want you to sin, tell them you will cosin and then get them off on a tangent.
I’m not saying it’s aliens, but it’s...
Did this ancient Babylonian tablet use a Z80?
Ah, the PDP-11 would have suited you.
A beach love triangle consists of two tangents and acute angel.
I cut my teeth on a PDP-7. Lots of switch flipping. 8K of ram.
Also progammed a PDP-11 as a ESI Laser controller. Did amazing things with that laser.
;o)
Also tortured myself on an IBM Series 1 for a year.
In the meantime, I laid hands on the SEL 810 & 840, the XDS Sigma 7 and 9, CDC 7600, and the UNIVAC 1108.
I really liked that big iron, and a wide assortment of mini-computers as well. Those seemed almost God-like. Computers of today are remarkable, stunning really. Common as BIC pens, and not as fun seeming as the old stuff. What youngsters miss is the clatter of that stupid ASR33.
Note: this topic is from . Thanks C19fan. Yesterday I saw a calculator with the trig functions -- at Dollar Tree.
