A 3,700-year old Babylonian clay tablet reveals an ancient method of constructing right-angled triangles that makes it the world’s oldest and most accurate trigonometric table.

Scientists from the University of New South Wales have shed light on the purpose of a mysterious clay tablet containing a trigonometric table created by the Babylonians a full 1,000 years earlier ...

The 3,700-year-old Babylonian tablet known as Plympton 322 turned out to be a trig table, expressed in ratios of the lengths of the sides of the triangles, rather than angles.

Trigonometry Table is a table that helps us to calculate the values of trigonometric ratios for common angles such as 0°, 30°, 45°, 60°, and 90°. But it is difficult to memorise the values.

The table of trigonometric values was made more than a thousand years before math historians thought trigonometry was invented. By Avery Thompson Published: Aug 25, 2017 2:59 PM EDT.

The Ancient Babylonians knew about a form of trigonometry more advanced than the modern-day version – about 1,000 years before its supposed invention by the Ancient Greeks, academics in ...

Ancient Babylonian trigonometry table teaches us something new A 3 700 year-old cuneiform clay tablet not only contains the world’s oldest trigonometric table; it is also the only completely ...

“Our research reveals that Plimpton 322 describes the shapes of right-angle triangles using a novel kind of trigonometry based on ratios, not angles and circles,” continued Mansfield.
