Can you please give the exact time line of trigonometry.


Hi Eugene,

Most of the development of trigonometry took place in classical Greek mathematics. Ptolemy wrote a trigonometry book that was unsurpassed until the time of Newton 1500 years later. You can trace the first usage of the terms we use such as trigonometry, sine and tangent at Earliest Known Uses of Some of the Words of Mathematics.
