Trigonometry and astronomy
Trigonometry is used everywhere in our lives, since the beginning of development in our civilisations, people have been researching about the three lengths that have mystified for centuries. Trigonometry can almost be seen everywhere. First of all though we need to know its international definition, trigonometry is a study of triangles and its sides and angles, the hypotenuse, the adjacent side and the opposite side. Trigonometry also has its different functions (cos, sin and tan) which have an essential relationship with the whole theme, they used in their specific situations when trying to uncover an unknown value. Mathematically it is mainly used for calculus (which is perhaps its greatest application), linear algebra, and statistics.The name its self comes from Greek descent, trigonometry itself means triangle and measure in Greek. They weren 't the actual discoverers of trig but they implied vast development and improvement in that subject for many years with the help of mathematicians and philosophers like Pythagoras, whom we know very well. The Greek used their findings with much of their architecture and geography but mainly for their interest in the sky, astronomy. Everything that may lie for away across the universe is part of astronomy, the studies of the universe, it heavily needs the help of trig for several reasons

With astronomy we 're dealing with matter far away in the universe we can only observe which is why trig plays such a big role. With trig we can start to calculate distances between matter and the angles at which they are facing the earth. This is how the Greeks started with the Pythagoras theorem (seen on the right). Although nowadays we mostly use the trig laws and theorems, SIN ( finding the rise O/H), COS( finding the run A/H) and TAN( finding the slope O/A). With these functions many immeasurable distances can be found by knowing two distances or a distance and an angle. Astronomers

    Trigonometry (from Greek trigōnon "triangle" + metron"measure"[1]) is a branch of mathematics that studies triangles and the relationships between their sides and the angles between these sides. Trigonometry defines the trigonometric functions, which describe those relationships and have applicability to cyclical phenomena, such as waves. The field evolved during the third century BC as a branch of geometry used extensively for astronomical studies.[2] It is also the foundation of the practical art…

    Teaching trigonometry using Empirical Modelling 0303417 Abstract The trigonometric functions sin(x), cos(x) and tan(x) are relationships that exist between the angles and length of sides in a right-angled triangle. In Empirical Modelling terms, the angles in a triangle and the length of the sides are observables, and the functions that connect them are the definitions. These well-defined geometric relationships can be useful when teaching GCSE-level students about the functions, as they…

    Trigonometry | Introduction to trigonometryAs you see, the word itself refers to three angles - a reference to triangles. Trigonometry is primarily a branch of mathematics that deals with triangles, mostly right triangles. In particular the ratios and relationships between the triangle's sides and angles. It has two main ways of being used: 1. In geometryIn its geometry application, it is mainly used to solve triangles, usually right triangles. That is, given some angles and side lengths,…

    Trigonometry is a field of mathematics first compiled by 2nd century BCE. Greek mathematician Hipparchus. The history of trigonometry and of trigonometric functions follows the general lines of the history of mathematics. Early study of triangles can be traced to the 2nd millennium BC, in Egyptian mathematics (Rhind Mathematical Papyrus) and Babylonian mathematics. Systematic study of trigonometric functions begins in Hellenistic mathematics, reaching India as part of Hellenistic astronomy. In Indian…

    Early trigonometry The ancient Egyptians and Babylonians had known of theorems on the ratios of the sides of similar triangles for many centuries. But pre-Hellenic societies lacked the concept of an angle measure and consequently, the sides of triangles were studied instead, a field that would be better called "trilaterometry".[6]The Babylonian astronomers kept detailed records on the rising and setting of stars, the motion of the planets, and the solar and lunar eclipses, all of which required…
