Trigonometry
Trigonometry (from Greek trigōnon "triangle" + metron "measure"[1]) is a branch of mathematics that studies triangles and the relationships between the lengths of their sides and the angles between those sides. Trigonometry defines the trigonometric functions, which describe those relationships and have applicability to cyclicalphenomena, 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 of surveying.
Trigonometry basics are often taught in school either as a separate course or as part of a precalculus course. The trigonometric functions are pervasive in parts of pure mathematics and applied mathematics

Trigonometry basics are often taught in school either as a separate course or as part of a precalculus course. The trigonometric functions are pervasive in parts of pure mathematics and applied mathematics such as Fourier analysis and the wave equation, which are in turn essential to many branches of science and technology.Spherical trigonometry studies triangles on spheres, surfaces of constant positive curvature, in elliptic geometry. It is fundamental to astronomy and navigation. Trigonometry on surfaces of negative curvature is part of hyperbolic

The surest foundation for the origin of science in its practical form is to be found in the ìco–rdination and standardization of the knowledge of common sense and of industry.î[1] One of the first occurrences of this co–rdination can be traced back to 2500 BCE in the form of edicts from the ancient Babylonian rulers, who issued royal standards of length, weight and capacity. Non-Semitic Sumerians also laid down the elements of mathematics and geometry at that time, making use of fractions, decimals, circles and radial angles. But knowledge as we know it today was tightly woven with magical notions, and as both spread westward they instilled in European thought a reverence for ìspecial numbers, their connections to the gods and the application of geometrical diagrams to the prediction of the future.î[2] As well, the ancient Babylonians were fascinated by the heavens. They were the first to make a map of the stars and associate them with animals like the Ram, Crab and Scorpion, names that we still use to this day. They also realized the periodicity and reliability of astronomical movement and phenomena, and were soon able to predict many of them. Tablets have been found dating to the sixth century BCE that predicted the relative positions of the sun and moon, as well as forecasted the occurrences of eclipses.[3] Out of all this knowledge the Babylonians built up a fantastic system of astrology, through which the starsówhich were thought to fix and foretell the course of human affairsówould give up their secrets.

For example Copernicus, Galileo, and Kepler were involved in a science called astronomy. Astronomy was the branch of science that deals with heavenly objects, space, and the physical universe as a whole. Different scientists invented different discoveries that changed our world today. Copernicus was a scientists who lived in Italy for many years, and discovered modern astronomy. Study and calculation led him to the conclusion that the earth turns upon its own axis, and, together with the planets, revolves around the sun, which led to his theory called the Copernican Theory. Another scientists who was involved in astronomy was Galileo. Galileo made one of the first telescopes, which was very powerful. He discovered the phases of Venus and sunspots, confirming that the sun rotates, and that the planets orbit around the Sun, not around the Earth. Galileo believed that these discoveries committed to the Copernican Theory. Kepler was another scientist involved in astronomy, he worked out the mathematical laws which govern the movements of the planets. He made it clear that the planets revolve around sun in elliptical instead of circular orbits. Kepler's investigations afterwards led to the discovery of the principle of gravitation. Vesalius and Harvey were involved in a science called anatomy. Anatomy was the the branch of science concerned with the bodily structure of humans, animals, and other living organisms. Vesalius studied in Italian medical schools, he was the founder of modern human anatomy, and wrote a very famous interesting books on human anatomy called De humani corporis fabrica. His discoveries consisted of the skeletal system, muscular system, vascular and circulatory system, nervous system, abdominal organs, the heart, and the brain. Vesalius discovered that the skulls mandible consists of only one bone. The sternum which is made up of three parts is also one of
What is Aztec Mathematics you may be asking yourself well let’s start from the beginning of Aztec Mathematics.Well there were these people called Aztecs who ruled central mexico before the spanish arrived they left the most extensive mathematical writing. They ruled until the spanish came and overthrew the empire. Aztecs used hand, heart and arrow symbols as fractional distances when they would calculate lands. The Aztecs existed around 1200 A.D.
An example of the difference in the abstract geometry and the measurement geometry is the sum of the measures of the angles of a trigon. The sum of the measures of the angles of a trigon is 180 degrees in Euclidian geometry, less than 180 in hyperbolic, and more than 180 in elliptic geometry. The area of a trigon in hyperbolic geometry is proportional to the excess of its angle sum over 180 degrees. In Euclidean geometry all trigons have an angle sum of 180 without respect to its area. Which means similar trigons with different areas can exist in Euclidean geometry. It is not possible in hyperbolic or elliptic geometry. In two-dimensional geometries, lines that are perpendicular to the same given line are parallel in abstract geometry, are neither parallel nor intersecting in hyperbolic geometry, and intersect at the pole of the given line in elliptic geometry. The appearance of the lines as straight or curved depends on the postulates for the space.
At this time, it was usual for all students at a university to attend courses on mathematics. These courses usually included the four mathematical sciences: arithmetic, geometry, astronomy and music. However, what w...
As my science fair topic, I chose to test the accuracy of using parallax to measure distance. I chose this topic because it relates to two of my favorite topics: mathematics and astronomy. Parallax uses a mathematical formula and is most commonly used to measure the distance between celestial bodies. From my research on parallax, I found how to measure it, and how to use the parallax formula to measure distances.
Greek mathematics began during the 6th century B.C.E. However, we do not know much about why people did mathematics during that time. There are no records of mathematicians’ thoughts about their work, their goals, or their methods (Hodgkin, 40). Regardless of the motivation for pursuing mathematical astronomy, we see some impressive mathematical books written by Hippocrates, Plato, Eudoxus, Euclid, Archimedes, Apollonius, Hipparchus, Heron and Ptolemy. I will argue that Ptolemy was the most integral part of the history of Greek astronomy.
Most of what we know concerning the development of trigonometry in India comes from influential works from the 4th – 5th century, known as the Siddhantas. There were five of these works with the most complete survivor being the Surya Siddhanta. These texts first defined the sine as the modern relationship between half an angle and half a chord. They also defined cosine, versine, and inverse sine. An Indian mathematician name Aryabhata (476 – 550 AD) later expanded on the developments of the Siddhantas in an influential and important work called the Aryabhatia. The Siddhantas and Aryabhatia contain the earliest surviving table of sine and versine values, in 3.75 degree intervals from 0 to 90 degrees, to an accuracy of 4 decimal places (History of Trigonometry).
Pythagoras held that an accurate description of reality could only be expressed in mathematical formulae. “Pythagoras is the great-great-grandfather of the view that the totality of reality can be expressed in terms of mathematical laws” (Palmer 25). Based off of his discovery of a correspondence between harmonious sounds and mathematical ratios, Pythagoras deduced “the music of the spheres”. The music of the spheres was his belief that there was a mathematical harmony in the universe. This was based off of his serendipitous discovery of a correspondence between harmonious sounds and mathematical ratios. Pythagoras’ philosophical speculations follow two metaphysical ideals. First, the universe has an underlying mathematical structure. Secondly the force organizing the cosmos is harmony, not chaos or coincidence (Tubbs 2). The founder of a brotherhood of spiritual seekers Pythagoras was the mo...
Mathematics is part of our everyday life. Things you would not expect to involve math
...roups that have been important to astronomy are the Akkadians, Egyptians, Chinese, Polynesians, and the Greeks. They used astronomy for navigation at sea, creating accurate calendars, making new inventions, and many more things! Some modern jobs in astronomy include Educational, Private industries, National Observatories and Laboratories. Also, some technical advances because of astronomy include many telescopes, tracking programs used by FedEx, and IRAF which is used to analyze computer systems. Even though astronomy is an incredibly interesting field, there are minimum job opportunities. Some of the jobs are included in the following fields: education, national observatories and laboratories, or in private industries. Astronomy has been the key to unlocking many new inventions and by connecting things from the past, to the present, and going into the future.
Ever wonder how scientists figure out how long it takes for the radiation from a nuclear weapon to decay? This dilemma can be solved by calculus, which helps determine the rate of decay of the radioactive material. Calculus can aid people in many everyday situations, such as deciding how much fencing is needed to encompass a designated area. Finding how gravity affects certain objects is how calculus aids people who study Physics. Mechanics find calculus useful to determine rates of flow of fluids in a car. Numerous developments in mathematics by Ancient Greeks to Europeans led to the discovery of integral calculus, which is still expanding. The first mathematicians came from Egypt, where they discovered the rule for the volume of a pyramid and approximation of the area of a circle. Later, Greeks made tremendous discoveries. Archimedes extended the method of inscribed and circumscribed figures by means of heuristic, which are rules that are specific to a given problem and can therefore help guide the search. These arguments involved parallel slices of figures and the laws of the lever, the idea of a surface as made up of lines. Finding areas and volumes of figures by using conic section (a circle, point, hyperbola, etc.) and weighing infinitely thin slices of figures, an idea used in integral calculus today was also a discovery of Archimedes. One of Archimedes's major crucial discoveries for integral calculus was a limit that allows the "slices" of a figure to be infinitely thin. Another Greek, Euclid, developed ideas supporting the theory of calculus, but the logic basis was not sustained since infinity and continuity weren't established yet (Boyer 47). His one mistake in finding a definite integral was that it is not found by the sums of an infinite number of points, lines, or surfaces but by the limit of an infinite sequence (Boyer 47). These early discoveries aided Newton and Leibniz in the development of calculus. In the 17th century, people from all over Europe made numerous mathematics discoveries in the integral calculus field. Johannes Kepler "anticipat(ed) results found… in the integral calculus" (Boyer 109) with his summations. For instance, in his Astronomia nova, he formed a summation similar to integral calculus dealing with sine and cosine. F. B. Cavalieri expanded on Johannes Kepler's work on measuring volumes. Also, he "investigate[d] areas under the curve" ("Calculus (mathematics)") with what he called "indivisible magnitudes.
There are many different types of triangles. Obtuse and acute triangles are the two different types of oblique triangles, triangles in which are not right triangles because they do not have a 90 degree angle.A special right triangle is a right triangle with some regular features that make calculations on the triangle easier, or for which simple formulas exist. Knowing the relationships of angles or ratios of sides of special right triangles allows one
Pythagoras made multiple contributions to math. He also contributed to science and philosophy. His contributions are seen as important today because they act as stepping stones in solving different problems.
