Abstract

The essay involves the birth of trigonometry and its subsequent development in ancient civilization. Although Greek and Babylonian mathematician laid the foundation of spherical trigonometry by discovering relations between spherical triangles and constructing tables of trigonometric functions but it was India who invented computational trigonometry which we use today to solve problems. Indian mathematician laid the foundation of plane trigonometry which was further carried out by Islam mathematician and finally became the modern day trigonometry.

Introduction

Trigonometry is a branch of mathematics which deals with its geometrical part to compute any unknown*…show more content…*

So we cannot say conclusively that trigonometry was born in Egypt.

Greek Civilization

The work that gave shape to modern trigonometry was done by Greek mathematicians. The father of trigonometry Hipparchus (190-120 BC) was the first to construct a table of values for trigonometric functions of different certain angles[ ]. Although he used geometrical formulas between various chords and its certain angles to calculate values but due to property of chord given below [ ] trigonometric formulas were known to him in equivalent chord form. However, later it was Ptolemy who modified the Hipparchus’s table into table of sine with angle ranging from*…show more content…*

So all in all, we can say that Hindu Mathematicians had done remarkable work on the Trigonometric functions and later their work was carried out by Arab mathematicians and there some of the words like jya and kot-ijya were converted to sine and cosine which we use today.

Application of Trigonometry:

The first and foremost application is in astronomy to calculate as explained earlier but today trigonometry is also used for other things like: Used in finding the heights of towers, mountains and also in oceanography department to calculate the height of tides in the ocean by using angle of elevation and line of sight of human eye. Used in navigation for ships, to calculate the structural load by finding out the slopes of surfaces and also in communication department for calculating various sine and cosine wave motions.

Conclusion:

Trigonometry has existed for at least two centuries in different form and although the initial aim of developing trigonometry was just to calculate the distance between celestial body but in Egypt and in the India trigonometry took a more computational form rather than geometric form in Greek period. Development of trigonometry was and will be a continuous process and therefore we can see how much work had gone into developing it into modern day

He was working through was is labeled as the “Testing Ideas” section, specifically the “Gathering Ideas” section. To interpret these ideas, Hoyle created a “creation field”. This creation field was “a fundamental feature of the universe. Although vague on the exact details of how the field worked, Hoyle asserted that every billion years or so production of about three atomic nuclei per square foot was needed.

First and foremost, let me tell you guys a story, long long time ago, the Greek Philosopher Pythagoras discovered the concept of harmony. In further studies of nature, he observed certain patterns and numbers reoccurring. Pythagoras believed that beauty was associated with the ratio of small integers. The discovered of Pythagos has result in the occurrence of the special ratio.

## Introduction To Graph Theory

1411 Words | 6 PagesINTRODUCTION Graph theory was born in 1736 when Euler, “The father of graph theory’’ solved Konigsberg Bridge problem. In 1847 Kirchhoff developed the theory of trees in order to solve the system of simultaneous linear equations which give the current in each branch and around each circuit of an electrical network. THE KONIGSBERG BRIDGE PROBLEM: Konigsberg (55.2 o North latitude and 22 o East longitude) was a city in Russia situated on the Pregel River, which served as the residence of the dukes of Prussia in the 16th century. Today, the city named Kaliningrad, is in Lithuania which recently separated from U.S.S.R. It serves as a major industrial and commercial centre of western Russia.

## Digital Inclinometer Research Paper

1344 Words | 6 Pages(3) General Uses of a Digital Inclinometer Generally speaking, there are many uses of a digital inclinometer in commercial or personal areas. In cameras, model aircrafts, some video games, and so on, digital inclinometers are widely used to make them work. Mechanical engineers also use digital inclinometers to measure the slope of a slant. Some engineers use digital inclinometers to estimate the height of certain things such as buildings, towers, etc. They use a projected image on a slope to tell the height of the items.

## X Ray Crystallography Research Paper

1233 Words | 5 PagesStarting in the following decade, James Watson and Francis Crick analyzed a crystalline model of DNA done by Rosalind Franklin, and used it to determine the double helix structure of DNA (Genetics: Unlocking the Secret to Life). This subsequently led to astonishing advancements in the genetic field, including the Human Genome Project. The project used crystallography and other methods to lead a global effort to identify 30,000 human genes and map human DNA (Human Genome Project). Despite being an almost unknown and forgotten technique, crystallography led to more well known and renowned accomplishments, such as Dorothy Hodgkin using the process to discover the structure of penicillin. Some may say this ingenuity didn’t affect the time period, and was not the most significant in the 1910’s.

## History Of The Periodic Table Essay

1114 Words | 5 PagesAs Döbriener only worked in relatively small groups of elements, Newlands wanted to compare all the existing elements to each other. Like a few scientists before him, Newlands organized his table in order of atomic weight. He grouped elements together in groups of seven and noticed that when doing so, the first element in each group had similar properties to the first elements in the other groups. This is where the law of Octaves was created (“History of the Periodic Table”). Some of the challenges faced by Newlands was the amount of criticism that he received.

In the world, there is a difference of body sizes that are as a result of a wide variety of ethnic backgrounds. Therefore, this is why anthropometric data can be collected and applied in a workplace to improve the safety, health and environment of employees. (Marras and Kim, 1971) conducted a research about the anthropometry of industrial population. Basically, this research was done to show the variation of population body measurement.

## Chemistry In Modern Medicine

777 Words | 4 PagesDuring the early 19th century, it was estimated around 60 elements had been found or discovered. Scientists scrambled to create a chart or visual representation aligning the elements commonly done by their atomic mass. In 1862, “a French geologist named Alexandre-Emile Béguyer de Chancourtois” organized the elements with mutual properties into trios down in a cylinder, which he named the telluric screw (Science Learning Hub). Béguyer de Chancourtois would be the first scientist to attempt to organize the elements into a system of representation and provided the foundation for the following years. Other scientists analyzed the patterns amongst the elements with similar properties, such as the English chemist “John Newlands, who in 1864 proposed the law of octaves” (Science Learning Hub).
