Greeks did not develop trigonometry, latest findings prove. Babylonians did.

Indo-Europeans are losing ground to Semites after a century and half long theories of Ancient hellenic supremacism
The reality is that Babylon was built upon the legacy of Sumer, civilisation starts with Sumer in the ME. And Sumer was neither Semitic nor IE. Probably they were a form of proto-Turkic people.

3,700-year-old Babylonian tablet rewrites the history of maths - and shows the Greeks did not develop trigonometry

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.

The true meaning of the tablet has eluded experts until now but new research by the University of New South Wales, Australia, has shown it is the world’s oldest and most accurate trigonometric table, which was probably used by ancient architects to construct temples, palaces and canals.
