Atan2
In computing and mathematics, the function (mathematics), function atan2 is the 2-Argument of a function, argument arctangent. By definition, \theta = \operatorname(y, x) is the angle measure (in radians, with -\pi 0, \\[5mu] \arctan\left(\frac y x\right) + \pi &\text x < 0 \text y \ge 0, \\[5mu] \arctan\left(\frac y x\right) - \pi &\text x < 0 \text y < 0, \\[5mu] +\frac &\text x = 0 \text y > 0, \\[5mu] -\frac &\text x = 0 \text y < 0, \\[5mu] \text &\text x = 0 \text y = 0. \end Instead of the tangent, it can be convenient to use the half-tangent as a representation of an angle, partly because the angle has a unique half-tangent, (See tangent half-angle formula.) The expression with in the denominator should be used when and to avoid possible loss of significance in computing . When an function is unavailable, it can be computed as twice the arctangent of the half-tangent . That is, |

Arctangent
In mathematics, the inverse trigonometric functions (occasionally also called ''antitrigonometric'', ''cyclometric'', or ''arcus'' 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. Notation Several notations for the inverse trigonometric functions exist. The most common convention is to name inverse trigonometric functions using an arc- prefix: , , , etc. (This convention is used throughout this article.) This notation arises from the following geometric relationships: when measuring in radians, an angle of radians will correspond to an arc whose length is , where is the radius of the circle. Thus in the unit circle, the cosine of x f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Attan
''Attan'' (), the national dance of Afghanistan, is a traditional dance originating from the tribal Pashtun regions. The dance is performed during weddings or other celebrations (engagements, weddings and informal gatherings). The Attan was also conducted by Pashtuns in times of war such as the British occupation and the Pashtun resistance movement, when Pashtuns used the dance to instil confidence and energy among warriors readying to battle the colonisers. It is now considered the national dance of Afghanistan, popularly carried by other ethnic groups in Afghanistan as well as by the Pashtun ethnic group in Pakistan. Attan is usually performed with a Dohol, which is a double-headed barrel drum. The dance can be anywhere from 5 to 30 minutes long. There are many different regional and tribal variations and styles of Attan, the most famous being Wardaki, Logari, Paktia, Khosti, Kandahari, and Herati. Depending on the region and tribe, there are different methods and styles of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
