I used to love the branch of mathematics called Trigonometry back in high school. What about you?
Trigonometry (from Greek "trigōnon", "triangle" and "metron", "measure") is a branch of mathematics that studies relationships involving lengths and angles of triangles.

History of trigonometry
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 began in Hellenistic mathematics, reaching India as part of Hellenistic astronomy. In Indian astronomy, the study of trigonometric functions flourished in the Gupta period, especially due to Aryabhata (sixth century CE). During the Middle Ages, the study of trigonometry continued in Islamic mathematics, hence it was adopted as a separate subject in the Latin West beginning in the Renaissance with Regiomontanus.
History of mathematics
The area of study known as the history of mathematics is primarily an investigation into the origin of discoveries in mathematics and, to a lesser extent, an investigation into the mathematical methods and notation of the past. Before the modern age and the worldwide spread of knowledge, written examples of new mathematical developments have come to light only in a few locales. From 3000 BC the Mesopotamian states of Sumer, Akkad and Assyria, together with Ancient Egypt and Ebla began using arithmetic, algebra and geometry for purposes of taxation, commerce, trade and also in the field of astronomy and to formulate calendars and record time.
Rational trigonometry
Rational trigonometry is a proposed reformulation of metrical planar and solid geometries (which includes trigonometry) by Canadian mathematician Norman J. Wildberger, currently an associate professor of mathematics at the University of New South Wales. His ideas are set out in his 2005 book "Divine Proportions: Rational Trigonometry to Universal Geometry". According to "New Scientist", part of his motivation for an alternative to traditional trigonometry was to avoid some problems that occur when infinite series are used in mathematics. Rational trigonometry avoids direct use of transcendental functions like sine and cosine by substituting their squared equivalents.
History of mathematical notation
The history of mathematical notation includes the commencement, progress, and cultural diffusion of mathematical symbols and the conflict of the methods of notation confronted in a notation's move to popularity or inconspicuousness. Mathematical notation comprises the symbols used to write mathematical equations and formulas. Notation generally implies a set of well-defined representations of quantities and symbols operators. The history includes Hindu–Arabic numerals, letters from the Roman, Greek, Hebrew, and German alphabets, and a host of symbols invented by mathematicians over the past several centuries.
Chinese mathematics
Mathematics in China emerged independently by the 11th century BC. The Chinese independently developed very large and negative numbers, decimals, a place value decimal system, a binary system, algebra, geometry, and trigonometry. Ancient Chinese mathematicians made advances in algorithm development and algebra. While the Greek mathematics declined in the west during the mediaeval times, the achievement of Chinese algebra reached its zenith in the 13th century, when Zhu Shijie invented the method of four unknowns. As a result of obvious linguistic and geographic barriers, as well as content, Chinese mathematics and the mathematics of the ancient Mediterranean world are presumed to have developed more or less independently up to the time when "The Nine Chapters on the Mathematical Art" reached its final form, while the "Writings on Reckoning" and "Huainanzi" are roughly contemporary with classical Greek mathematics.
Pi
The number () is a mathematical constant. Originally defined as the ratio of a circle's circumference to its diameter, it now has various equivalent definitions and appears in many formulas in all areas of mathematics and physics. It is approximately equal to 3.14159. It has been represented by the Greek letter "" since the mid-18th century, though it is also sometimes spelled out as "pi". Being an irrational number, cannot be expressed exactly as a common fraction (equivalently, its decimal representation never ends and never settles into a permanent repeating pattern). Still, fractions such as 22/7 and other rational numbers are commonly used to approximate .
PW-Sat
PW-Sat is a series of satellites that includes the first Polish artificial satellite which was launched 13 February 2012 from ELA-1 at Guiana Space Centre aboard Italian-built Vega launch vehicle during its maiden voyage. PW-Sat1's mission was to test experimental elastic solar cells, as well as an orbital decay technology consisting of a "tail" designed to speed re-entry. It was expected to last for 1 year. PW-Sat1 was a type of CubeSat satellite constructed by the Faculty of Power and Aeronautical Engineering of Warsaw University of Technology in cooperation with the Space Research Centre of the Polish Academy of Sciences.

Trigonometry
Trigonometry (from Greek "trigōnon", "triangle" and "metron", "measure") is a branch of mathematics that studies relationships involving lengths and angles of triangles. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. The 3rd-century astronomers first noted that the lengths of the sides of a right-angle triangle and the angles between those sides have fixed relationships: that is, if at least the length of one side and the value of one angle is known, then all other angles and lengths can be determined algorithmically. These calculations soon came to be defined as the trigonometric functions and today are pervasive in both pure and applied mathematics: fundamental methods of analysis such as the Fourier transform, for example, or the wave equation, use trigonometric functions to understand cyclical phenomena across many applications in fields as diverse as physics, mechanical and electrical engineering, music and acoustics, astronomy, ecology, and biology.
Triangle
A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices "A", "B", and "C" is denoted formula_1. In Euclidean geometry any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane (i.e. a two-dimensional Euclidean space). In other words, there is only one plane that contains that triangle, and every triangle is contained in some plane. If the entire geometry is only the Euclidean plane, there is only one plane and all triangles are contained in it; however, in higher dimensional Euclidean spaces this is no longer true.
Pythagorean theorem
In mathematics, the Pythagorean theorem, also known as Pythagoras's theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. The theorem can be written as an equation relating the lengths of the sides "a", "b" and "c", often called the "Pythagorean equation": where "c" represents the length of the hypotenuse and "a" and "b" the lengths of the triangle's other two sides. Although it is often argued that knowledge of the theorem predates him, the theorem is named after the ancient Greek mathematician Pythagoras ( 570–495 BC) as it is he who, by tradition, is credited with its first recorded proof.
Integer triangle
An integer triangle or integral triangle is a triangle all of whose sides have lengths that are integers. A rational triangle can be defined as one having all sides with rational length; any such rational triangle can be integrally rescaled (can have all sides multiplied by the same integer, namely a common multiple of their denominators) to obtain an integer triangle, so there is no substantive difference between integer triangles and rational triangles in this sense. Note however, that other definitions of the term "rational triangle" also exist: In 1914 Carmichael used the term in the sense that we today use the term Heronian triangle; Somos uses it to refer to triangles whose ratios of sides are rational; Conway and Guy define a rational triangle as one with rational sides and rational angles measured in degrees—in which case the only rational triangle is the rational-sided equilateral triangle.
Triangulation station
A triangulation station, also known as a triangulation pillar, trigonometrical station, trigonometrical point, trig station, trig beacon, or trig point, and sometimes informally as a trig, is a fixed surveying station, used in geodetic surveying and other surveying projects in its vicinity. The nomenclature varies regionally; they are generally known as "trigonometrical" or "triangulation stations" in North America, "trig points" in the United Kingdom, "trig pillars" in Ireland, "trig stations" or "points" in Australia and New Zealand, and "trig beacons" in South Africa; "triangulation pillar" is the more formal term for the concrete columns found in the UK.
Special right triangle
A special right triangle is a right triangle with some regular feature that makes calculations on the triangle easier, or for which simple formulas exist. For example, a right triangle may have angles that form simple relationships, such as 45°–45°–90°. This is called an "angle-based" right triangle. A "side-based" right triangle is one in which the lengths of the sides form ratios of whole numbers, such as 3 : 4 : 5, or of other special numbers such as the golden ratio. Knowing the relationships of the angles or ratios of sides of these special right triangles allows one to quickly calculate various lengths in geometric problems without resorting to more advanced methods.
List of triangle inequalities
In geometry, triangle inequalities are inequalities involving the parameters of triangles, that hold for every triangle, or for every triangle meeting certain conditions. The inequalities give an ordering of two different values: they are of the form "less than", "less than or equal to", "greater than", or "greater than or equal to". The parameters in a triangle inequality can be the side lengths, the semiperimeter, the angle measures, the values of trigonometric functions of those angles, the area of the triangle, the medians of the sides, the altitudes, the lengths of the internal angle bisectors from each angle to the opposite side, the perpendicular bisectors of the sides, the distance from an arbitrary point to another point, the inradius, the exradii, the circumradius, and/or other quantities.

Yup'ik
The Yup'ik or Yupiaq (sg & pl) and Yupiit or Yupiat (pl), also Central Alaskan Yup'ik, Central Yup'ik, Alaskan Yup'ik (own name "Yup'ik" "Yupiik" "Yupiit" ), are an Eskimo people of western and southwestern Alaska ranging from southern Norton Sound southwards along the coast of the Bering Sea on the Yukon-Kuskokwim Delta (including living on Nelson and Nunivak Islands) and along the northern coast of Bristol Bay as far east as Nushagak Bay and the northern Alaska Peninsula at Naknek River and Egegik Bay. They are also known as Cup'ik by the Chevak Cup'ik dialect-speaking Eskimos of Chevak and Cup'ig for the Nunivak Cup'ig dialect-speaking Eskimo of Nunivak Island.
Yup'ik clothing
Yup'ik clothing (Yup'ik "aturaq" "aturak" "aturat" , "aklu", "akluq", "un’u" ; also, "piluguk" in Unaliq-Pastuliq dialect, "aklu", "cangssagar", "un’u" in Nunivak dialect) refers to the traditional Eskimo-style clothing worn by the Yupik people of southwestern Alaska. Also known as Cup'ik clothing for the Chevak Cup'ik-speaking people of Chevak and Cup'ig clothing for the Nunivak Cup'ig-speaking people of Nunivak Island. The traditional clothing system developed and used by the Eskimo peoples is the most effective cold weather clothing developed to date. Yup'ik women made clothes and footwear from animal skins (especially hide and fur of marine and land mammals for fur clothing, sometimes birds, also fish), sewn together using needles made from animal bones, walrus ivory, and bird bones such as front part of a crane's foot and threads made from other animal products, such as sinew.
Yup'ik cuisine
Yup'ik cuisine ("Yupiit neqait" in Yup'ik language, literally "Yup'iks' foods" or "Yup'iks' fishes") refers to the Eskimo style traditional subsistence food and cuisine of the Yup'ik people from the western and southwestern Alaska. Also known as Cup'ik cuisine for the Chevak Cup'ik dialect speaking Eskimos of Chevak and Cup'ig cuisine for the Nunivak Cup'ig dialect speaking Eskimos of Nunivak Island. This cuisine is traditionally based on meat from fish, birds, sea and land mammals, and normally contains high levels of protein. Subsistence foods are generally considered by many to be nutritionally superior superfoods.
Yup'ik language
Central Alaskan Yup'ik or just Yup'ik (also called Yupik, Central Yupik, or indigenously Yugtun) is one of the languages of the Yupik family, in turn a member of the Eskimo–Aleut language group, spoken in western and southwestern Alaska. Both in ethnic population and in number of speakers, Central Alaskan Yup'ik is the largest of the languages spoken by Alaska Natives. As of 2010 it was also the second largest aboriginal language in the United States in terms of numbers of speakers. Yup'ik should not be confused with the related language Central Siberian Yupik spoken in Chukotka and St. Lawrence Island.
Natural scientific research in Canada
This article outlines the history of natural scientific research in Canada, including physics, astronomy, space science, geology, oceanography, chemistry, biology, and medical research. Neither the social sciences nor the formal sciences are treated here. The early European explorers were responsible for charting much of what would become the east and west coasts of Canada as well as the Arctic. John Cabot, the Italian explorer sailing under the English flag made two voyages to North America in 1497 and 1498 along the coast of what is now called Newfoundland. Gaspar Corte-Real, the Portuguese explorer, is thought to have explored the area along the Newfoundland, Labrador and Greenland coasts in 1500 and 1501.
Yup'ik dancing
Yup'ik dancing (or dance) or Yuraq, also Yuraqing (Yup'ik "yuraq" "yurak" "yurat" ) is a traditional Eskimo style dancing form usually performed to songs in Yup'ik, with dances choreographed for specific songs which the Yup'ik people of southwestern Alaska. Also known as Cup'ik dance for the Chevak Cup'ik dialect speaking Eskimos of Chevak and Cup'ig dance for the Nunivak Cup'ig dialect speaking Eskimos of Nunivak Island. Yup'ik dancing is set up in a very specific and cultural format. Typically, the men are in the front, kneeling and the women stand in the back. The drummers are in the very back of the dance group.
Women in science
britan  Women have made significant contributions to science from the earliest times. Historians with an interest in gender and science have illuminated the scientific endeavors and accomplishments of women, the barriers they have faced, and the strategies implemented to have their work peer-reviewed and accepted in major scientific journals and other publications. The historical, critical and sociological study of these issues has become an academic discipline in its own right. The involvement of women in the field of medicine occurred in several early civilizations, and the study of natural philosophy in ancient Greece was open to women.
