Who is the father of trigonometry?

mathematician Hipparchus The first known table of chords was produced by the Greek mathematician Hipparchus in about 140 BC. Although these tables have not survived, it is claimed that twelve books of tables of chords were written by Hipparchus. This makes Hipparchus the founder of trigonometry.

What was included in the book The almagest?

The Almagest /ˈælmədʒɛst/ is a 2nd-century Greek-language mathematical and astronomical treatise on the apparent motions of the stars and planetary paths, written by Claudius Ptolemy ( c. AD 100 – c. 170). It is also a key source of information about ancient Greek astronomy.

Do all planets have epicycles?

In both Hipparchian and Ptolemaic systems, the planets are assumed to move in a small circle called an epicycle, which in turn moves along a larger circle called a deferent. Introduction.

Body Sun
Mean size (in Earth radii) 1,210
Modern value (semimajor axis, in Earth radii) 23,480
Ratio (modern/Ptolemy) 19.4

How did Ptolemy determine the positions of the planets in his geocentric model?

A Geocentric View. Ptolemy synthesized Greek knowledge of the known Universe. Based on observations he made with his naked eye, Ptolemy saw the Universe as a set of nested, transparent spheres, with Earth in the center. He posited that the Moon, Mercury, Venus, and the Sun all revolved around Earth.

Why Ptolemy modified the geocentric model?

Ptolemy had to make one more adjustment to the model to allow it to fit historic observations of the stars and planets and thus be able to accurately predict their future positions. Even when epicycles were added, the position of the planets was not where the model predicted they would be.

Who made the star catalog?

Hipparchus Hipparchus completed the first known catalog in 129 bce, giving the celestial longitudes and latitudes of about 850 stars. This work was enlarged and improved by Ptolemy, the Alexandrian astronomer and mathematician, in his Almagest (c. 140 ce).

Who is Ptolemy and what did he do?

Claudius Ptolemy was a Greek mathematician, astronomer and geographer. Much of medieval astronomy and geography were built on his ideas: his world map, published as part of his treatise Geography in the 2nd century, was the first to use longitudinal and latitudinal lines.
