The birth of trigonometry would occur around 140 B.C. when the Greek mathematician Hipparchus produced the first table of chords. For the Greeks, it was important to know the ratio of any chord on the circle to the diameter of the circle for astronomical purposes. daily school schedule template kids

WebbThe precision of photographic and visual measurements is about 0.05–0.1 magnitude. The brightest star in the sky, Sirius, has a magnitude V = -1.46; the weakest belong to the 23rd stellar magnitude. The magnitude of the sun is V = -26.78, while that of the full moon is V = -12.71.

For example, since Theon is only summarizing Adrastus, and possibly not doing that particularly well, there is no strong reason to suppose that Theon actually knew how Hipparchus solved the problem. Thus, in absence of further information, the actual method used by ...

Webbin a similar manner to Hipparchus, Ptolemy innovated upon Hipparchus’ method by inscribing regular polygons inside a circle and calculating the resulting chords from each polygon. By combining this with a method to find the chord subtended by half the arc of a known chord, Ptolemy calculated chord lengths accurate to six decimal places [2].
