Ptolemy created the earliest tables of trigonometry functions that were found. His mathematical methods have been used to solve problems in astronomy.
The largest contribution Claude Ptolemy made to trigonometry was the table containing the lengths of chords in a circle. This is one of the oldest tables still used in trigonometry today.
Aristolte and Ptolemy sorry if i did not spell it right
The main contribution for which Ptolemy is famous is his discovery that the earth revolved around the sun. This was known as the heliocentric theory (and it competed with Catholic Church teaching of the time, which held that the earth was the center of the solar system or geocentric).
Ptolemy contributed to science and astronomy by developing the theory of the Earth. He was the first person to view the solar system as a heliocentric system instead of a geocentric system.
There are a number of factors that influenced Ptolemy. He was mainly influenced by the intellectual development of Hipparchus of Bithynia among other philosophical aspects of life.
chemistry
There is no Contribution of Thales in the field of trignometry.........
nothing
hipparchus
He defined the spherical triangle
He introduced coordinated geometry
Not everyone but trigonometry is needed in the field of construction under certain circumstances
Trigonometry has the most application in Engineering and Physics.
spherical and plane trigonometry? :p
Aristolte and Ptolemy sorry if i did not spell it right
An important contribution by Menelaus of Alexandria was his works on geodesics.
Centuries ago, Islam created the mathematics of 'Trigonometry'.
Physics, aeronautics, and astronomy all rely heavily on trigonometry.
