Around 190 BC Hipparchus was born in Nicaea in Bithynia (Now know as Turkey.) Hipparchus was the 1st astronomer to figure out how far the Sun was from the Earth. There are records from 147 to 127 BC of his achievements with trigonometry. During the 18th century Lazare Carnot, a French statesman and mathematician, showed that the whole layout of trigonometry can be deduced from his own formulas. Hipparchus catalogue was completed in about 129 BC, it had listed about 850 stars. He had spent most of his life in Rhodes in the observatories. Hipparchus was a powerful influence on Claudius Ptolemy who centuries later his works had considerable impact on the development of Western culture. Hipparchus was also one of the most influential astronomers of antiquity, yet very little information available about him still survives.
Hipparchus did his studying in

Given OA = 160 mm OB = 40 mm AC = 240 mm Using the position analysis and trigonometry rules, the equation is different for every group of input angle value, θ. For 0º < θ ≤ 90º x = 70 + AC sin[pic] For 90° < θ ≤ 180º x = 70 + AC sin[pic] For 180º < θ ≤ 270º x = 70 – AC sin[pic] For 270º < θ ≤ 360º x = 70  AC…

He founded trigonometry and scientific geography. He discovered precession of equinoxes and invented methods of fixing terrestrial positions by circles of latitude and longitude. He located 850 stars and divided the stars that he could see into classes of apparent brightness. Hipparchus estimated the size and distance of the…

The Father of Trigonometry
3474 Words  14 PagesThe first trigonometric table was apparently compiled by Hipparchus, who is now consequently known as "the father of trigonometry."[3] Sumerian astronomers introduced angle measure, using a division of circles into 360 degrees.[4]They and their successors the Babylonians studied the ratios of the sides of similar triangles and discovered some properties of these ratios, but did not turn that into a systematic method for finding sides and angles of triangles. The ancient Nubians used a similar methodology…

Around 127BC, Hipparchus figured out the equinoxes and calculated the length of the year to about 6.5 minutes of the correct value, started the understanding of trigonometry (A Mathematical Chronology,2014). From 1AD to 2002, a lot of things started to change for mathematics. Around 1AD, a Chinese mathematician started using the decimal fractions…

He also developed the theory that our solar system is "geocentric," meaning that the Sun, moon, and other planets revolve around Earth. Even though he was incorrect, his theory was very advanced for his time (Bertman, 130). Hipparchus created trigonometry, which he used to calculated Earth's distance from the moon. He also discovered that the…

1882 Words  8 PagesIntertextuality in Robert Kroetsch's Seed Catalogue The late poet John Donne said, "No man is an island." Donne passed away in the earliest part of the seventeenth century, and yet he recognized an idea upon which much of modern philosophy and literary criticism is built. Donne said, in effect, that any individual man is nothing outside the body of mankind; Donne thereby supports a theory of cultural subjectivism. In the field of literary criticism, particularly modern and postmodern criticism…

Hipparchus (fl. 145130 BC) He was one who put forth strong arguments against the heliocentric theory of Aristarchuson the grounds that a mathematical system of eccentrics and epicycles seemed to account more logically for the movement of the heavens (he had a very strong influence on Ptolemy who took up his work several centuries later) and did not suffer from a theory which required the earth to move. This to Hipparchus flew solidly in the face of common sense…
