Hipparchus and trigonometry
Did you know?
Webb4 sep. 2024 · Hipparchus obtained some of the values for his table from the properties of special geometric figures, such as the 30 ∘ − 60 ∘ − 90 ∘ triangle and the 45 ∘ − 45 ∘ − 90 ∘ triangle. The rest of the values were obtained from those already known by using trigonometric identities and approximation. WebbThe first trigonometric table was apparently compiled by Hipparchus of Nicaea (180 – 125 BCE), who is now consequently known as "the father of trigonometry." Hipparchus was the first to tabulate the corresponding values of arc and chord for a series of angles.
WebbThe Greek astronomer Hipparchus (d. c. 127 bc) was the first to compose a table of trigonometric functions (based on the chords in a circle), which he calculated at increments of 7° 30′. Ptolemy (d. c. ad 145) improved on Hipparchus’s tables by calculating the values at 30′ increments. Webb26 aug. 2016 · Lived c. 190 BC - c. 120 BC.

WebbThe sole trigonometric function used by the ancient Greeks is the chord, which is closely related to the sine function (Toomer 7). What is known from Ptolemy is that … WebbIn an imitation of Hipparchus’ approach, we define a function crd which returns the length of the chord in a given circle sub-tended by a given angle. Translated to modern language, crda = 2r sin a 2 a r crd a crd(180 a) Hipparchus chose a circle with circumference 360° (in fact he used 60 360 = 21600 arcminutes): the result is that r = 21600
