According to the researchers, Plimpton 322 is a trig table, similar to the ones seen in every high school math textbook, except Plimpton 322 uses triangles instead of circles and angles.

Describing their work in Historica Mathematica, the researchers call the tablet "a trigonometric table of a completely unfamiliar kind and... ahead of its time by thousands of years." What made it ...

Three and Four Place Tables of Logarithmic and Trigonometric Functions. By James Mills Peirce. 16 pp. (Boston: Ginn Brothers, 1871.) ...

Trigonometry is the branch of mathematics that explains the relationship between sides and angles of a triangle. In a right angled triangle the three sides are perpendicular, base and hypotenuse ...

SYDNEY, AUSTRALIA—A 3,700-year-old cuneiform tablet housed at Columbia University is inscribed with the world’s oldest and most accurate working trigonometric table, according to a report in ...

Our new research, published in Historia Mathematica, shows that the Babylonians were able to construct a trigonometric table using only the exact ratios of sides of a right-angled triangle.

Now researchers from the University of New South Wales are calling it one of the oldest and possibly most accurate trigonometric tables of the ancient world. Findings published in the journal ...

When applied to an angle measure, the three trigonometric functions produce the various combinations of ratios of side lengths. In other words: The tangent of angle A = the length of the opposite ...
