## Who invented the 0?

Brahmagupta”Zero and its operation are first defined by [Hindu astronomer and mathematician] Brahmagupta in 628,” said Gobets.

He developed a symbol for zero: a dot underneath numbers..

## Who invented math?

Beginning in the 6th century BC with the Pythagoreans, the Ancient Greeks began a systematic study of mathematics as a subject in its own right with Greek mathematics. Around 300 BC, Euclid introduced the axiomatic method still used in mathematics today, consisting of definition, axiom, theorem, and proof.

## Is 0 a real number?

Answer and Explanation: Yes, 0 is a real number in math. By definition, the real numbers consist of all of the numbers that make up the real number line. The number 0 is…

## Who invented homework?

Roberto NevelisRoberto Nevelis of Venice, Italy, is often credited with having invented homework in 1095—or 1905, depending on your sources. Upon further inspection, however, he seems to be more of an internet myth than an historical personage.

## Who invented Cos?

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. He provided accurate trigonometric tables and expressed the theorem in a form suitable for modern usage.

## What are the 9 trig identities?

Sine, Cosine and TangentSine Function:sin(θ) = Opposite / HypotenuseCosine Function:cos(θ) = Adjacent / HypotenuseTangent Function:tan(θ) = Opposite / Adjacent

## Why was trigonometry invented?

The ancient Greeks transformed trigonometry into an ordered science. … Most of the early advancements in trigonometry were in spherical trigonometry mostly because of its application to astronomy. The three main figures that we know of in the development of Greek trigonometry are Hipparchus, Menelaus, and Ptolomy.

## Who Found exam?

Henry Fischel’ If we were to go by historical sources, then exams were invented by an American businessman and philanthropist known as Henry Fischel somewhere in the late 19th century. However, some sources attribute the invention of standardized assessments to another man by the same name, i.e. Henry Fischel.

## What is the full form of mathematics?

full form of mathematics. Explanation: M-miracle of nature. A-art of arithmetic. T-tool of knowledge.

## Who is the father of trigonometry?

Hipparchus of NicaeaHipparchus of Nicaea (/hɪˈpɑːrkəs/; Greek: Ἵππαρχος, Hipparkhos; c. 190 – c. 120 BC) was a Greek astronomer, geographer, and mathematician. He is considered the founder of trigonometry but is most famous for his incidental discovery of precession of the equinoxes.

## How was trigonometry used in the past?

The prime application of trigonometry in past cultures, not just ancient Greek, is to astronomy. Computation of angles in the celestial sphere requires a different kind of geometry and trigonometry than that in the plane. The geometry of the sphere was called “spherics” and formed one part of the quadrivium of study.

## What jobs use trigonometry?

Manufacturing Industry. Trigonometry plays a major role in industry, where it allows manufacturers to create everything from automobiles to zigzag scissors. Engineers rely on trigonometric relationships to determine the sizes and angles of mechanical parts used in machinery, tools and equipment.

## Who first invented trigonometry?

Hipparchus of NicaeaThe first trigonometric table was apparently compiled by Hipparchus of Nicaea (180 – 125 BCE), who is now consequently known as “the father of trigonometry.” Hipparchus was the first to tabulate the corresponding values of arc and chord for a series of angles.

## Who found zero in India?

AryabhataArab merchants encountered the zero in India and carried it to the West. What is widely found in textbooks in India is that a mathematician and astronomer, Aryabhata, in the 5th century used zero as a placeholder and in algorithms for finding square roots and cube roots in his Sanskrit treatises.

## Why do we need trigonometry?

Trigonometry is, simply put, the study of triangles and the lengths and angles of their sides. As one of the most important fields of mathematics, particularly for careers that are built around calculating angles, a working knowledge of trigonometry and its uses is important for students of all ages.

## What country is first in math?

Singapore is the smartest country in the world, followed by Hong Kong, South Korea, Taiwan, Japan, Finland, Estonia, Switzerland, Netherlands and Canada rounding out the top 10.

## Where is trigonometry used in real life?

Trigonometry can be used to roof a house, to make the roof inclined ( in the case of single individual bungalows) and the height of the roof in buildings etc. It is used naval and aviation industries. It is used in cartography (creation of maps). Also trigonometry has its applications in satellite systems.

## Why Sine is called sine?

In mathematics, the sine is a trigonometric function of an angle. … The word “sine” (Latin “sinus”) comes from a Latin mistranslation by Robert of Chester of the Arabic jiba, which is a transliteration of the Sanskrit word for half the chord, jya-ardha.
