geometry of the sphere (called spherics) were compiled into textbooks, such as the one by Theodosius (3rd or 2nd century bce) that consolidated the earlier work by Euclid and the work of Autolycus of Pitane (flourished c. 300 bce) on spherical astronomy.
Who is the father of spherical geometry?
As a result, parallel lines do not exist. Figure 24.1 A model of spherical geometry. The mathematician Bernhard Riemann (1826? 1866) is credited with the development of spherical geometry.
Who invented spherical trigonometry?
In the 13th century, Nasīr al-Dīn al-Tūsī was the first to treat trigonometry as a mathematical discipline independent from astronomy, and he developed spherical trigonometry into its present form.
Who discovered hyperbolic geometry?
The first published works expounding the existence of hyperbolic and other non-Euclidean geometries are those of a Russian mathematician, Nikolay Ivanovich Lobachevsky, who wrote on the subject in 1829, and, independently, the Hungarian mathematicians Farkas and János Bolyai, father and son, in 1831.
Where did spherical trigonometry originate from?
Spherical trigonometry is of great importance for calculations in astronomy, geodesy, and navigation. The origins of spherical trigonometry in Greek mathematics and the major developments in Islamic mathematics are discussed fully in History of trigonometry and Mathematics in medieval Islam.

Who is called Father of trigonometry?
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.
Did aryabhatta invented trigonometry?
His definitions of sine (jya), cosine (kojya), versine (utkrama-jya), and inverse sine (otkram jya) influenced the birth of trigonometry. He was also the first to specify sine and versine (1 − cos x) tables, in 3.75° intervals from 0° to 90°, to an accuracy of 4 decimal places.
Who discovered Euclidean geometry?
Euclidean geometry, the study of plane and solid figures on the basis of axioms and theorems employed by the Greek mathematician Euclid (c. 300 bce). In its rough outline, Euclidean geometry is the plane and solid geometry commonly taught in secondary schools.
Who is the father of non-Euclidean geometry?
Carl Friedrich Gauss, probably the greatest mathematician in history, realized that alternative two-dimensional geometries are possible that do NOT satisfy Euclid's parallel postulate – he described them as non-Euclidean.
Who started non-Euclidean geometry?
Riemann (1826-1866) - are traditionally associated with the discovery of non-Euclidean geometries.
Who invented 0?
The first modern equivalent of numeral zero comes from a Hindu astronomer and mathematician Brahmagupta in 628. His symbol to depict the numeral was a dot underneath a number.
Who invented cosine?
In the 15th century, Jamshīd al-Kāshī, a Persian mathematician and astronomer, provided the first explicit statement of the law of cosines in a form suitable for triangulation.
Who invented calculus?
Sir Isaac Newton was a mathematician and scientist, and he was the first person who is credited with developing calculus.
What is true spherical geometry?
Spherical geometry is the study of geometric objects located on the surface of a sphere. Spherical geometry works similarly to Euclidean geometry in that there still exist points, lines, and angles. ... ① There are no parallel lines in spherical geometry. In fact, all great circles intersect in two antipodal points.
What is a line called in spherical geometry?
Basic Points
A line: a line on a sphere is called an arc due to the shape of a sphere. It is also the shortest distance between two points on the sphere . If an arc is extended, it will form a great circle. A great circle, however is the end of the lines path.
Is spherical geometry infinite?
A Line in Spherical Geometry is a great circle on the sphere, that is, a circle that divides the sphere into two equal halves. For example, the equator is a great circle. A Line (great circle) is considered infinite (actually boundless) because one can travel on it indefinitely.
Who created geometry?
Euclid was a great mathematician and often called the father of geometry. Learn more about Euclid and how some of our math concepts came about and how influential they have become.
Who are the mathematicians who tried to prove the 5th postulate?
al-Gauhary (9th century) deduced the fifth postulate from the proposition that through any point interior to an angle it is possible to draw a line that intersects both sides of the angle.
Is spherical geometry non-Euclidean?
Each Non-Euclidean geometry is a consistent system of definitions, assumptions, and proofs that describe such objects as points, lines and planes. The two most common non-Euclidean geometries are spherical geometry and hyperbolic geometry. ... In spherical geometry there are no such lines.
Who is Euclid India?
Euclid (/ˈjuːklɪd/; Ancient Greek: Εὐκλείδης – Eukleídēs, pronounced [eu̯. kleː. dɛːs]; fl. 300 BC), sometimes called Euclid of Alexandria to distinguish him from Euclid of Megara, was a Greek mathematician, often referred to as the "founder of geometry" or the "father of geometry".
Who is the father of mathematics?

What is Euclid famous for?
Euclid, Greek Eukleides, (flourished c. 300 bce, Alexandria, Egypt), the most prominent mathematician of Greco-Roman antiquity, best known for his treatise on geometry, the Elements.

Who discovered zero aryabhatta?
Aryabhata is the first of the great astronomers of the classical age of India. He was born in 476 AD in Ashmaka but later lived in Kusumapura, which his commentator Bhaskara I (629 AD) identifies with Patilputra (modern Patna). Aryabhata gave the world the digit "0" (zero) for which he became immortal.
