Trigonometry is a branch of mathematics that deals with the study of triangles and the relationships between their sides and angles. It has a wide range of applications, including in engineering, physics, and astronomy. The study of trigonometry can be traced back to ancient civilizations, such as the Egyptians and the Babylonians, who used it for practical purposes such as land measurement and construction. However, the father of trigonometry is generally considered to be the ancient Greek mathematician Hipparchus of Nicaea.

Hipparchus was born in Nicaea, a city in modern-day Turkey, around 190 BC. He is known for his contributions to mathematics and astronomy, and is considered one of the greatest astronomers of the ancient world. In addition to his work in trigonometry, he also made significant contributions to the development of the calendar and the measurement of time.

One of Hipparchus's most notable achievements in trigonometry was his development of the first known trigonometric table, which provided values for common trigonometric functions such as sine, cosine, and tangent. This table was a major advancement in the study of trigonometry and allowed for more accurate calculations to be made. In addition, Hipparchus also developed the concept of chord, which is a line segment connecting two points on a curve. This concept is still used in modern trigonometry and has played a significant role in the development of calculus.

Hipparchus's work in trigonometry and astronomy was not well known during his lifetime, but his ideas were later rediscovered and developed by other mathematicians and astronomers. For example, the mathematician Ptolemy, who lived in the 2nd century AD, built upon Hipparchus's work and further developed the field of trigonometry.

Despite the many contributions of Hipparchus to the field of trigonometry, his work was largely forgotten for centuries. It was not until the Renaissance that his contributions were rediscovered and his work began to be recognized as the foundation of modern trigonometry. Today, Hipparchus is considered the father of trigonometry and his contributions to the field continue to be studied and admired by mathematicians and astronomers around the world.

## Who is the father of trigonometry?

Hippocras's biographies were written by following people. The academy was incorporated in 2015 to cater to the needs of students, who aim to crack competitive exams by connecting with the best brains around. Spherical trigonometry also owes its development to his efforts, and this includes the concept of the six fundamental formulas for the solution of spherical right-angled triangles. Prediction of a solar eclipse, i. The six trigonometric capabilities are sine, cosine, secant, cosecant, tangent and cotangent. Because from that time it won't be possible to know even about the overall galaxy.

## Who is father of trigonometry?

The devices like gnomon, the armillary sphere, the astrolabe, and many more were been discovered by Hipparchus. } Ptolemy used these results to create his trigonometric tables, but whether these tables were derived from Hipparchus' work cannot be determined. Trigonometry traces its roots back to Ancient Babylon and Egypt. La Spezia: AgorĂ Edizioni: 145â€”156. Archive for History of Exact Sciences 57: 465â€”502. With these values and simple geometry, Hipparchus could determine the mean distance; because it was computed for a minimum distance of the Sun, it is the maximum mean distance possible for the Moon. With this method, as the parallax of the Sun decreases i.
