    Trigonometry, in the form of a table of chord lengths in a circle, was probably used by Claudius Ptolemy of Alexandria to obtain the value of π given in the Almagest (circa 150 CE). [ 68 ] Advances in the approximation of π (when the methods are known) were made by increasing the number of sides of the polygons used in the computation.
