## Is trigonometry useful in life?

It is used in oceanography in calculating the height of tides in oceans.

The sine and cosine functions are fundamental to the theory of periodic functions, those that describe the sound and light waves.

Calculus is made up of Trigonometry and Algebra.

…

Also trigonometry has its applications in satellite systems..

## Who is the No 1 mathematician of the world?

Isaac Newton is a hard act to follow, but if anyone can pull it off, it’s Carl Gauss. If Newton is considered the greatest scientist of all time, Gauss could easily be called the greatest mathematician ever.

## Who is the mother of math?

1. HYPATIA. Hypatia (c. 355–415) was the first woman known to have taught mathematics.

## Who is the founder of trigonometry?

HipparchusA corollary of this is that, before Hipparchus, astronomical tables based on Greek geometrical methods did not exist. If this is so, Hipparchus was not only the founder of trigonometry but also the man who transformed Greek astronomy from a purely theoretical into a practical predictive science.

## Who was the father of mathematics?

mathematician ArchimedesGreek mathematician Archimedes is widely considered by many to be the “father of mathematics.” He is regarded as one of the leading scientists in classical antiquity and is credited with designing numerous innovative machines, including the screw pump and siege engines.

## What is the importance of 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.

## Why is trigonometry so hard?

In fact it’s rather basic mathematics. However if all you know is arithmetic and basic linear algebra then yes trigonometry seems more difficult. The reason is that unlike linear algebra (solving linear equations) trigonometry is non-linear which makes the identities between multiples of angles non-trivial.

## What jobs use trigonometry?

Trigonometry spreads its applications into various fields such as architects, surveyors, astronauts, physicists, engineers and even crime scene investigators.

## How is sin calculated?

In a right triangle, the sine of an angle is the length of the opposite side divided by the length of the hypotenuse. Try this Drag any vertex of the triangle and see how the sine of A and C are calculated. The sine function, along with cosine and tangent, is one of the three most common trigonometric functions.

## Who was the 1st mathematician?

Thales of MiletusOne of the earliest known mathematicians was Thales of Miletus (c. 624–c. 546 BC); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed.

## When did Hipparchus discover trigonometry?

Hipparchus, (b. Nicaea, Bithynia–d. after 127 BC, Rhodes?), Greek astronomer and mathematician who discovered the precession of the equinoxes, calculated the length of the year to within 6 1/2 minutes, compiled the first known star catalog, and made an early formulation of trigonometry.

## Which country invented trigonometry?

The Babylonians could measure angles, and are believed to have invented the division of the circle into 360º. However, it was the Greeks who are seen as the original pioneers of trigonometry. A Greek mathematician, Euclid, who lived around 300 BC was an important figure in geometry and trigonometry.

## 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.

## What is sin equal to?

Always, always, the sine of an angle is equal to the opposite side divided by the hypotenuse (opp/hyp in the diagram). The cosine is equal to the adjacent side divided by the hypotenuse (adj/hyp). (1) Memorize: sine = (opposite side) / hypotenuse. cosine = (adjacent side) / hypotenuse.

## What is the value of sine?

The exact value of sin 180 is zero. Sine is one of the primary trigonometric functions which helps in determining the angle or sides of a right-angled triangle. It is also called trigonometric ratio.
