In geometry, a hypotenuse is the side of a right triangle opposite the right angle. It is the longest side of any such triangle; the two other shorter sides of such a triangle are called catheti or legs. The length of the hypotenuse can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the two legs. Mathematically, this can be written as , where a is the length of one leg, b is the length of another leg, and c is the length of the hypotenuse.
In mathematics, the inverse trigonometric functions are the inverse functions of the trigonometric functions, under suitably restricted domains. Specifically, they are the inverses of the sine, cosine, tangent, cotangent, secant, and cosecant functions, and are used to obtain an angle from any of the angle's trigonometric ratios. Inverse trigonometric functions are widely used in engineering, navigation, physics, and geometry.

The SR-50 was Texas Instruments' first scientific pocket calculator with trigonometric and logarithm functions. It enhanced their earlier SR-10 and SR-11 calculators, introduced in 1973, which had featured scientific notation, squares, square root, and reciprocals, but had no trig or log functions, and lacked other features. The SR-50 was introduced in 1974 and sold for US$170. It competed with the Hewlett-Packard HP-35.
Cold Ashby is a village and civil parish in West Northamptonshire in England. At the time of the 2001 census, the parish's population was 255 people, increasing to 278 at the 2011 census.
A triangulation station, also known as a trigonometrical 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 stations or triangulation stations in North America, trig points in the United Kingdom, trig pillars in Ireland, trig stations or trig points in Australia and New Zealand, and trig beacons in South Africa.
Collaroy Plateau is a suburb of northern Sydney, in the state of New South Wales, Australia. Collaroy Plateau is 22 kilometres north-east of the Sydney central business district, in the local government area of Northern Beaches Council and is part of the Northern Beaches region. Collaroy Plateau was designated as a separate suburb in 1977 with a postcode of 2098, but was reassigned as a locality within Collaroy in 1984, with the postcode changing to 2097 as part of Collaroy. In 2001 all localities were renamed Urban Places. In 2011 Collaroy Plateau, along with Wheeler Heights, was re-established as a suburb by the Geographical Names Board of NSW, after lobbying by the community, who had never ceased considering it to be a suburb since its loss of that title in 1984.
Sarah Louise Palin is an American politician, commentator, author, and reality television personality who served as the ninth governor of Alaska from 2006 until her resignation in 2009. She was the 2008 Republican vice presidential nominee under U.S. Senator John McCain.
The American adult animated sitcom Family Guy has been the target of numerous taste and indecency complaints. The show is known to include offensive jokes including racial humor and violent, gory, and disturbing images.
The following outline is provided as an overview of and topical guide to trigonometry:
Trigonometry is a branch of mathematics concerned with relationships between angles and side lengths of triangles. In particular, the trigonometric functions relate the angles of a right triangle with ratios of its side lengths. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. The Greeks focused on the calculation of chords, while mathematicians in India created the earliest-known tables of values for trigonometric ratios such as sine.
Todd Mitchell Palin is an American businessman who was the first gentleman of Alaska from 2006 to 2009. He is the former husband of former Alaska governor Sarah Palin, the 2008 Republican vice presidential nominee with John McCain.
Sarah Palin is an American politician, commentator and author who served as the ninth Governor of Alaska from 2006 to 2009. She was the Republican Party nominee for Vice President in the 2008 presidential election alongside Arizona Senator John McCain.
Sarah Palin, while serving as Governor of Alaska, was nominated as the first female candidate of the Republican Party for Vice President of the United States. Following the nomination, her public image came under close media scrutiny, particularly regarding her religious perspective on public life, her socially conservative views, and a perceived lack of experience. Palin's experience in foreign and domestic politics came under criticism among conservatives as well as liberals following her nomination. A poll taken by Rasmussen Reports just after the Republican National Convention in the first week of September 2008 found that Palin was more popular than either Barack Obama or John McCain; however, this perception later reversed. At the same time, Palin became more popular among Republicans than McCain. A February 2010 ABC News/Washington Post poll showed 71% of Americans felt Palin lacked the qualifications necessary to be President of the United States.
"Extra Large Medium" is the 12th episode of the eighth season of the animated comedy series Family Guy. Directed by John Holmquist and written by Steve Callaghan, the episode originally aired on Fox in the United States on February 14, 2010. In "Extra Large Medium", Peter discovers that he has supposedly developed "extrasensory perception" (ESP) after his two sons, Chris and Stewie, go missing during a family hike in the woods. Soon after being rescued, Chris decides to ask out a classmate at his school, named Ellen, who has Down syndrome, and eventually takes her on a romantic date, which he goes on to regret. Meanwhile, Peter begins performing psychic readings, but is eventually discovered to be faking his ability once he is approached by the town's police force.
Andrea Fay Friedman was an American actress.
Jyā, koṭi-jyā and utkrama-jyā are three trigonometric functions introduced by Indian mathematicians and astronomers. The earliest known Indian treatise containing references to these functions is Surya Siddhanta. These are functions of arcs of circles and not functions of angles. Jyā and koti-jyā are closely related to the modern trigonometric functions of sine and cosine. In fact, the origins of the modern terms of "sine" and "cosine" have been traced back to the Sanskrit words jyā and koti-jyā.
In trigonometry, it is common to use mnemonics to help remember trigonometric identities and the relationships between the various trigonometric functions.
Townsville Astronomical Trigonometrical Station is a heritage-listed triangulation station at Stanton Hill, North Ward, City of Townsville, Queensland, Australia. It was designed by Robert Hoggan and built in 1891. It is also known as Townsville Observatory. It was added to the Queensland Heritage Register on 21 October 1992.
The District Council of Willunga, was a local government area in South Australia seated at Willunga from 1853 until 1997.
